GW2 PvP is in an atrocious state. The devs do not listen to the upset PvP community. PvP is filled with cheese condi and AI builds and cheese sustain builds that cannot be killed except by the cheese condi/AI builds.

The last major balance patch was I think mid last year, and it didn't change anything worthwhile. Basically, devs have abandoned PvP balance in favor of bi-weekly churning out of PvE content to keep the PvE'ers interested.
