@Fe-Tarkus
By "backing," do you mean Background Information?
Sort of. Just my thoughts behind the abilities.

How long is the animation for 1st skills if they can be cancelled halfway through? By "cancel" do you mean shield canceling, dodge canceling, or something else?
Any sort of cancel. Shield/dodge come to mind. The power is instant like a remedy capsule though.

Are the 2nd abilities instant casts? Or how long is the animation?
Instant casts, yes. Try using the chat command in-game to see how long it would be.

I don't know about the 2nd part of "Shield Overdrive"... it's too much of an attack imo.
I view it more as a counter to swarming enemies. It also puts more priority on gunning down guardians instead of roflstomping their shield with a flourish.
Granted the drain might be a bit much. Perhaps it would passively drain the shield as fast as a recon's cloak does normally?

Isn't "maximum!" +6? Or is it specifically different for statuses and they're 2/3 for some reason... wat
On weapons, yes. For armors and helmets, it goes on a scale of Low->Medium->High->Maximum!, so it's a scale of up to +4.

So they have universal cooldowns like BS abilities?
Yes. We shouldn't have a guardian be status walking while draining your shield.

@Holy-Nightmare
Why not give recon the perfect hide ability
That's not really something that is activated like a sprite ability, more something the shield could do passively. Feel free to post that suggestion.

@Jungle-Sword

1. I'm trying to cover class weaknesses instead of boosting their strengths. Strikers combat weakness is bombs, recons swords, and guardians guns.
2. So? A recon can just as easily deathmark you after freezing you and unleash an acheron charge. This is more for when your shield is down and you have nothing to defend yourself with.
3. Recons and Guardians do indeed rely on their shield. Strikers rely on their boost too. As of the current game, when a striker is without a boost, their dodge is their defense. The other two classes don't have that, and if you look at all the skills as a whole, you'll notice that all those defenseless moments are covered.
4. Guardians can still use this tactic with double defense - they can remain invincible as long as a status bomb is active. However, a Guardian's weakness it its gun penalty. Bombs often call for the use of a gunner to assist in, so if only a guardian is near, they can power up their defense and jump onto the bombs. They will get +7 to all statuses under my suggestion, and it only lasts 4 seconds, so they'll be status walking for long enough to either disable a bomber or be trapped in their bombs.
5. And strikers don't already have a huge advantage over guardians? No other classes can easily reach the level of overpowered that striker can reach. For other classes, it takes much more prediction and investment into the class, whereas Striker you pick up your sword and health trinkets and go. Besides, a striker can only use the reset/any abilities every 30 seconds if they are only using the dash reset.

Looking back on stuff a bit now I'm realizing I should have put a different ability on guardians that would compensate for the gun ASD. Maybe the cooldown times would be longer for the recon/guardian stuff too - the striker is supposed to be fast paced and as such should have the shorter cooldown times of the mix.
Again, any ideas are welcome here. If you can identify any weakness in a class, perhaps that would be something to throw into the mix. I don't address the striker's health penalty directly (I sort of do through defense stuff) so maybe an ability that would passively give the striker health for several seconds with a long cooldown?

'strikers combat weakness is bombs, recons swords and guardians guns'
uhh the only WEAKNESS is the striker bomb CTI
guards ASD low on guns is a weakness? .....not a very big one
neither with the recons, asi low isn't a weakness
Combat weakness. The weakness doesn't have to be all that big of a weakness to be one. If you have no ASI on your swords, then good luck trying to be the best recon-swordsman. Same for guardian - without nullifying the weakness you can't rely primarily on that weapon type - and this is because each class is centered around two weapon types. Not saying you can't overcome those weaknesses, but that doesn't make them any less of a weakness.

actually a recon CAN'T add deatmark AND then charge up, maybe only vs a chaos clone
Recons have a passive +2 CTR to all weapons. With a level 10 acheron you have CTR: VH. I admittedly don't do this as a recon because acheron isn't really how I like to play in PvP.

And as for your scenarios, scenario 1 sounds like the teamwork this game needs. Remember that the strikers hitting the other strikers protected by the guardian shield will break the shield, and thus the protective measures it gives to both the guardian and their allies is gone. Scenario 2 does sound like a problem, however every recon should have at least one gun on them. They could also be bombing the point, in which case shield overdrive wouldn't be very effective.
You can throw your own balancing ideas into the mix too. Constructive criticism is welcome as that's what makes a suggestion grow. Perhaps you can suggest something that makes the shield overdrive more fair? Maybe the draining powers are only active once the shield breaks and isn't being hit? That would prevent an overdrive from affecting a bomber on the point when a guardian is going invincible from mist bombs.

When criticism is constructive it's healthy. When it's just "that sounds bad. it's bad. i don't like it" and doesn't say why, that's when it's not healthy.

But any other ideas for abilities for each class? Maybe cooldown time and skill lifetime revamps?

Adjusting health trinkets is another good fix for lockdown, however it isn't an ability we could activate battle-sprite style. Another possible passive to throw into the mess is adjusting the base defense values, with striker at 70, recons at 100 and guardians at 120. This would help a bit honestly, but if that's the case then we should probably make actual defense of armors scale similarly.

But as I said, that is more of something that are passives to lockdown. Perhaps Holy-Nightmare could make their lockdown thread about possible "passives" and throw a few ideas around in there?
(Seriously, nothing's stopping you from making a thread that is for the improvement of a currently unbalanced minigame, especially since it's not going down the same road that this one is taking)

But perhaps if those health precautions are taken into effect, a striker ability could be a pill dropper, where when you kill a player they will drop a pill on the ground for the appropriate tier instead of a heart? You could replace the dodge reset idea with this. It could work similarly to a seraphynx heart attack, or work completely differently and have the effect be a status inflicted upon players when hit by a striker with the ability active. 30-35 second cooldown and effect lasts for 7 seconds?

It really only makes sense for certain classes to have certain battle sprites. I mean, we have one for each class right now. Only, that would mean we're given a temporary battle sprite, probably leveled to scale with the tier and with no ultimates and normal damage.

At the same time, that would allow strikers to have even more health from the sprite perk. I'm not sure about you, but having +18 health as a striker seems like a death warrant for everyone else.

I'd like family bonuses to be incorporated into lockdown. Maybe a sprite could replace family bonuses with "damage bonus vs striker: medium" and whatnot. Honestly I'd like two families to be for each lockdown shield, but that's another suggestion entirely.

But remember, some of the things sprites do right now are for other classes. Know what would be unfair? A striker with a seraphynx shield, or a hexing haze. Or a guardian with a shadow cloak.

If you're going to do battle sprites, we'd either need a new one for lockdown that everyone gets, or limit our current sprites per class. Recon can already cloak, so having a shadow cloak on a recon wouldn't break them as much as it would for others. A guardian can also turn themselves and allies invincible, so having a seraphynx shield wouldn't break them too much. Strikers are already great in close quarters, so a fire barrier wouldn't break them too much.

If each sprite only had its primary attack, that could be doable, but at that point is it really worth it?
Also, keep in mind if we can bring our own sprites into lockdown, you would constantly be thrown into tier 3 on accident because you had that sprite equipped. And many people wouldn't be able to play on the same playing field as other people who have battle sprites. The suggestion I've proposed gives abilities to cover weaknesses of the class, but only temporarily and are available to everyone always. Throwing battle sprites into the mix not only directly unbalances things, but it turns lockdown into even more of a grind, because everyone will grab a maskerwraith, and that's a long time investment for an already unbalanced PvP minigame.

Dunno why I didn't comprehend that entirely before. Still doesn't solve the issue of classes honestly.

Also, a recon with that seraphic aura bug would be the last thing I want for myself.
