Got to agree with Pyre - Failed grapples, lunges that go through bots & pros or make you lunge right off the map :cry:
To pick one, I would go with Sniper. Nothing more rage inducing than lining up a headshot, and then pulling the trigger, only to miss because of UNHOLY LAG THAT CAME OUTTA NOWHERE.
It rarely does work anyway for me anyway :? I just use jetgun for deathblossoms and turret kills. Assassin is probably the worst, followed by sniper.
I've coined her the Sometimes Assassin. Sometimes my lunge and 'X' skill will work, sometimes it doesn't. Smoke bomb will either launch me into the upper atmosphere and stuck on the ground, at least it gives the entire smoke bomb back to me again so i can get more and more frustrated with each failed attempt.
The tank's jet gun lag is pretty annoying, especially when YOU SEE AND HEAR IT HIT THEM and nothing happens. However, under lag, the assassin is absolutely insufferable. Grapples don't register, stutter stepping, shurikens go through people (I've heard they do even on host), and smoke bomb jumps don't...jump. I rarely play the assassin, and those are the reasons why.
Sniper but only on a certain type of lag that makes scoping in impossible u scope in it unscopes it scopes in again it unscopes ugh bad times forever in need of host migration
