Only talk about WvW:Warrior is the only class that you can go fully glass but still as bunky as a real bunker ( e.g. FB).The major defense of warrior come from trait/utility but not gears, so you can go full offensive.Defense trait alone give u invul + stab, paired with featherfoot you are immune to everything for 5 seconds. Utility get EP + BS pair with healing signet, you get another 5 seconds god mode. so together you have 10 seconds god mode every 40 seconds. it's enough to output all your burst then leave safely, that's why you always see 1 single warrior dare to rush into a 20+ zerg trolling around then escape right away.Warrior is the frontline of the frontlines.
