only exception being the wd/w which is a tank
Common misconception. It CAN tank but it is not "strictly" a tank. Wd/w gets nearly as much patk as w/wd and gets more pdmg. I do more dps on wd/w then i do w/wd, which is a dps class. So wd/w is not "just" a tank. It can do either.
w/p (with 70 elite) is quite strong, but I don't know how it compares to w/wd in terms of dps output. Slash hits twice every use (50 elite) for like 15 or 20s something like that, you get near perma bonus rage regen from bloodlust, and the 70 elite makes bloodlust also increase attack speed by 7 or 8% which can be refreshed. It also gains some odd support skill, increases dmg of party members next 4 attacks or something, and has an hp buff (that stacks with other hp buffs). w/p can be quite strong, but again, I can't give direct comparison to others since I haven't personally played w/p.
