Guild Wars 2

So people keep saying that condition damage is useless in WvW (large group fights).
I can see why, but on the other hand what else can we do?

Izerker+ mirror images+ shatter. Use GS and Staff. Fire or Torment sigils for AOE. We also can veil, feedback, clear cond, give stability, portal bomb.
If you are looking for a lot of bags in zerg fights or large scale event farming in PVE mesmer really bad with it.
