I don’t understand. It’s simple, and I say this after playing the game for years and having done everything in the game, every single dungeon and raid: guard is unfortunately forced to only tank, because they can’t produce enough dps compared to conqs and dts.
It’s not that I don’t like guard. I raid T6 with a guard these days. It’s just a fact; conqs can switch spec and do decent dps, and dts can do it by just changing gear, but guards do poor dps even in polearm spec.
About the other issue, I agree with M: s&s guard has more aggro (and survivability) than polearm.
It’s pretty much like the sin, who can’t AoE, while barb has decent AoE. You can’t expect to do everything with every class. But, coming back to tanks, DT revamp made it an OP multiclass. They could do everything if they only could throw big heals as well and spammable AoE hexes or something. But I think the problem is really the fact mobs and bosses in most easy encounters have very little protection, making DT’s the kings of aggro and casters the kings of dps. Only T5, T6, SC and maybe some other place I can’t remember are more balanced in that regard.
