Just bcoz a rogue killed u PVP it doesn't mean Rogues r OP, each & every class has got a unique set of stats, skills & combos which r different from each other. Its up to player's playing skills & tactic to know what to use when.
Now there is thread saying Nerf Rogue for sake of PVP just bcoz of some good combos later after (IF) the class receives a nerf another thread pops up saying Buff rogues for sake of PVE as the party gets slow bcoz of the nerf.
