Lag. Way too much Post Mortem kills. Far too often, I'll hit someone with a killing blow and move onto another target only to get killed by my original target, who then dies from my hit immediately afterwards. I've been gaming online since the 90s, so I'm really used to playing with lag... but in this day and age, such lag shouldn't be a thing. Also, Bladedancers. I -blam!-ing hate Bladedancers.
