Just to be clear. You're saying a stealth single target burst class is parsing on par with other classes that don't have the same opening advantages... That seems ok to you OP?
Seems to me the problem lies within players like yourself that are content with serving as stationary PVE(P) dummies for Operatives. OH GOSH DARN AN OP JUMPED ON ME ah well I'll just stay where I am and do nothing to prevent them from killing me. Hilarious, isn't it?
