On my pvp server, I'm making my alt Sniper so I can actually engage in pvp, instead of using my healer, so I was wondering which would be "best" for PvP? I know that Engineer is AOE, while Marksmanship is Single-target burst, but I also hear that Engineer is more mobile. I'm just confused on the general subject, because I hear one is the best and another isn't, vice versa.
