Q:
How are Warriors in Pvp, WvW in general.
Guardian. Easy to survive, brings good amount of support and utility to any group or zerg and has the capability to roam fairly well.
But to answer your question, based on skill, gear, and spec those three class will all do well roaming or small group. The warrior will be the best for a zerg as the ranger doesn’t bring much to a zerg besides dps and a water field. I have yet to see a solid zerging thief build besides poison share, but even then it’s more effective for small ops.
Can never have enough heavies in a zerg for the melee train.
What do you want to do in WvW?
Guardian / Warrior / Thief / Necromancer
