I would have assumed that also! But i have 'attempted' to talk to the high level Jap players for advice about this, and a level 70RNG told me something along the lines of a warrior being good for a rng because of the berserk... atleast that is what i think he was trying to say. Its hard to fully follow as he didn't translate well, but for some reason he mentioned it. Thats why i was hoping i could find a Rng/War or a Rng/Drk from english speaking country who might be able to explain the effects better to me :-D
