as per title,
it is POINTLESS to make assumptions about class or game balance because something happened in WvW. this is the one environment in the game where outgearing your opponent is possible. this is the one environment in the game where a player can have World buffs (the orbs of power) that are totally unrelated to their class and make them fight like supermen.
if you are going to make a post trying to argue something about class mechanics DO NOT REFERENCE WvW. it is not a balanced environment. intentionally. WvW is intentionally not balanced. anything you say about class balance as a result of something that happened in WvW is basically a bogus claim.
