1: Misfireing skills - Cant begin to imagine how many have died because my heals didnt work.. I believe its tied to the number of input the game can process or something.. I see this a lot more when shooting (space) and manouvering (with the mouse) at the same time as Im trying to fire off a few heals.
2: Mousebug - I know its possible to get rid of it by rebooting the game, but I still hate it.
3: Smacktalkers - Generally I ignore them, but I *SO* hate the ones that win one game and smacktalk from start to end, and then the next that they lose, they complain about OPd this or OPd that.
Repeatedly mashing a key only to find that the skill has failed to activate (usually around the time I or someone I should have healed explodes) is, was, and perhaps always will be incredibly frustrating. Also, being that I use the NumPad to fly, instead of the mouse, tab targeting has been a big hindrance at times.
On a personal note, my own overall inconsistent performance in PvP is rather humbling. I can go from the top of the chart to the bottom in consecutive matches. I'd be perfectly happy to hover around the middle!
On a side note, LMAO @ not being able to teabag.
Yeah, I know what you mean. Sometimes I think "Hey, maybe I now actually grasp how to fly escorts" and then "man, I am the worst escort player ever". It's a little more consistent with Cruisers and Science Vessels. of course, a lot has to do with the opposition I face and how they fight (and if they target me).
Tri-cobalts misfiring is also incredibly annoying.
But powers not activating at all and then going on cooldown in general is just about the worst of the current system. It is made even worse because you get the audio-cue that it activated, and sometimes the animation on the button, but nope, didn't feel like it today.
