I'm a BM sniper myself and i am usually allways at the top of damage in WZs by a large margin, but im allways active as well, not losing any time in there. I guess i have to use 24 different abilities all the time in a WZ, not counting hotkeys for relics and OOC heal etc. I do fine.
Snipers are cool, but there are some issues. The rooting disables us from going to cover needs to go, since its an effective "stun" on a Sniper, especially MM.
Pure white damage would be fine if other classes had the same, but it seems most classes got majority of yellow damage abilities, so this is kinda unfair, unless regular damage has any advantage over yellow which i don't know of.
Cover needs some reworking i guess. Entrench bugging on some abilities, especially in PvE (maybe it is intended). I also don't like ballistic dampeners and instant snipe beeing removed as soon as you go out of cover due to a small misplacement, but i understand why the internal CD needs to be there. Must be a way around it though, not punishing beeing quick on the move..
For future PvP i guess poisions should get some dispell protection or punishment for dispelling them, if not a whole spec can be ruined with 1 click, which allready happens now, just not in random WZs.
I play as lethality mostly. running around 500 exp.
