The PvP is fine, there is something there for everyone. sPvP, tPvP and WvWvW are all fantastic.
which class do you like the least?
I really don't care for the Engineer. It has way too much utility to the point that it's overwhelming and I don't like the kits being pure weapon replacements instead of augmentations. They should have made it like the thief where the kit changed your 4 and 5 skills instead of everything. They look fun as hell in WvW but I can't bring myself to level one.
