Latency screws me over in about every match some way or another. Minor or major.

-I'm suddenly turned away from my opponent even though I locked on them.
-Fetter Ward constantly screws me over. I use it. 5 secs later I'm being stunned.
-Other PCs popping up everywhere. Fighting someone face to face. Suddenly they are miles away.
-Skills hangs. I use them, 2 secs later they chose to obey.
-When chasing someone, even though I sprint/fists of wind, my attacks never goes off (again locked on target). If there is too much movement chances are I'm screwed.

Most of the time it's ok though. It's really only in huge skirmishes like 72 slaughter. Rarely in PvE. My internet connection and computer should be more than good enough to handle this game. But I guess everyone experience some sort of latency in 72 PvP.
