It would make sense though that warrior has weapons with so similar functions (aside for single-target vs AoE, which is pretty important) because he has a lot of weapons to pick from especially melee. You get to pick out of 5 melee burst skills, that is, 2 from 2H weapons and 3 from 3 main-hand weapons.
Not counting off-hands, 5 different melee styles is hard to come up with, and from what I tried the melee weapons felt pretty different. 2H is AoE, swords is mobility, mace/hammers is control/shutdown, and axe is damage (AoE only).
I wish guardian had more weapon choices. Bow and axe would be nice.
