Why would you use deathmark in 1v1 and not vs a group?

Mind you, I've never ventured out of T3, but tactically, I see more value in deathmarking a group than in solo combat:
When you're dealing with a group, you usually want to reduce their numbers by either sending them running or killing them off, and deathmark can only contribute to that, from what I've seen.

If you deathmark 2/3 enemies near a point, everyone assumes you will attack the deathmarked people and the un-marked ones are more likely to have their guard down and give you a free hit while everyone else goes in a panic. And even if you go and attacked the deathmarked ones, you have a better chance of actually killing them than if you just go for a regular hit.

Of course, I'm assuming here that you attack between warning/deathmark, so you're not just sitting uselessly in cloak while you attempt to mark everyone in the area.

well, the OP said NOT to use it vs a group:

-Do not bother using the Death Mark for 2 knights or more. Death Mark is only good for 1-on-1.

I'm all for using it whenever possible, but I can't see the argument for why you would specifically NOT use it lol.

Just to throw out some things. I am not necessarily right.

1. I say use the cloak sparingly. Learn when to use the cloak and when not to to conserve it. Strikers will laugh at you when you run out of cloak on a base and they effortlessly chase you down.
2. I concur.
3. I concur.
4. No. Unless you are a solo player Death mark helps your team fight better. Your strikers will benefit from taking down enemies with greater ease. A guardian that protects you while you death mark people as a striker takes down the enemy is a good combo.
5. Mind games are essential to success.
6. No comment
7. See point 1.
8. There's a reason recons get charge time reduction medium for everything and charge time reduction very high for bombs. It's a waste if you're not taking advantage of the bomb charge time. Freezing someone and unleashing Shockburst charges is more fun than you think.

Hammer or Sealed is a good heavy sword to use. Combo sparingly, hit once, dodge while cloaked, attack. I don't recommend Arc Razor.
Nightblades deal heavy damage, as do elemental Brandishes. I would rather use a Flourish/Barb for actual fights. Heavy swords are better than you think if you have the skill for it.
Antiguas irritates many people and personally I will target an antigua user first. Antiguas are also not for group fights, you'll end up messing up your frontline striker's attacks (usually). A blaster is good though, as are alchemers and forgive me, pulsar.

Combos are Tantamount to suicide and should be used sparingly. Any skilled Hammer or Toothpick user will easily beat you with shield cancelling if you don't know what you are doing.
Method 2, aka Shield cancel. It works for many things. A thing to note about recon: Interrupting your enemies before they attack is important if not essential to survival.
