Disclaimer: I haven't played LD for over two months, I believe. I'm running off my memory as well as logic. Also, when I say 'I', 'you', 'them', I'm talking generally, assuming that all players are equally skilled. (More or less)
Okay, just saying this because I thought it reaaally addresses the issue of Lock Down. I've been watching Extra Credits lately, and this one is on Counter Play. The gist of it is that mechanics you add must be fun for the people wielding the mechanics as well as those who are getting targeted by those mechanics.
Let's think about...Heart Trinkets. I've said before how bad these are, but now I can put formal terms to them. Basically, let's say I'm a guy with 10 more health then you or her or them. What's this do for me? Well, it opens several new options to me. I can now stand (for a little longer) in your barrage of attacks, and I can probably kill a few more people. Or, if I'm a Striker, I could take those hits and then dash back to the base, and restore all that lost health. This means I can stay in the game more a greater percentage of the match without really being more crafty or skilled.
For those without trinkets, what then? Much like sniping, they have to be incredibly careful how they play, or stick with teammates. (As good as that last solution sounds, it never happens.) This is rather unfair, and reduces what I can do. I can no longer defend my team well, because their players outlive me and/or my buddies. I can no longer sneak up behind someone and 'assassinate' them. Heck, I can't even duel them to the death because they simply have an upper hand. And, if my buddies have trinkets, there is no way I can easily carry as much weight as they can.
In other words, Heart Trinkets causes a disparity between players who have trinkets and those who don't. They are bad for the overall experience. In the end, this is terrible even for those with heart trinkets, because they now have no one to beat up.
Rather than making a great wall of text greater, I will challenge you: Find other issues. Not even come up with solutions. I just want to see how much this community can find.
As one last word, I think that these issues either should be resolved or LD should be dropped, because it really hurts the experience for everyone. For those players who will never even want to play LD, they see the list of people waiting for LD and think "This is an empty game." Need I say more?
Couter Play!
Might want to get an "n" in there. That's an issue I found.
Honestly there are a lot of quick fixes (at least in terms of words) that many have come up with. For the most part it's because trinkets and UVs completely alter the game from an idea of balance to one of paying players win.
However, the solution isn't to "disable trinkets and UVs and AT". Really the fix is to create better alternatives. Give us better trinkets to use in those slots. Make Lockdown-specialized ones for all I care, or just in general shield related ones.
Else changes to the actual trinket could happen. Percentage based would be nice. My thoughts were that they could be percentage based (i.e. 5* gives 33% more health, 4* 27%, 3* 21%, 2* 15%, 1* 9*). Health from heart trinkets would be a paler hue, thus the non-full pip values wouldn't confuse players (also the fact that they increase in size would be good). True love lockets remain a static +6 pips. On top of that add the other trinkets in, such as "shield focus increased" which increases the power of your shield (not shield bar. Think: faster strikers, instant deathmarks, faster healing. In PvE it could be more defense), "shield power increase" (increased shield bar), and "shield recharge increased".
Sorry, I'm not really one to like to sit around complaining when I could be fixing something. Maybe I should try to stay out of this thread now. :\
