Geez, it's 2am here, idiot. I have to be considerate of everyone asleep. And what's there to say when I'm mopping up and soloing Banshees and Brutes?
That's because of lag :( Most of the time headshots wouldn't kill, or despite hitting in melee I wouldn't get them off me, or... even worse, after a sure kill hit, I'd read "assist" points, without ever touching them before.
Concerning the last two games as a vanguard, I just suck.
