you need to rephrase the question
its not 'how strong' - try with 'how weak'
if you want to play pvm you have the following choices:
hammerdong, pangolin, nova, lightning, blizzard, fb, mosaic, trap, java, fire druid
Sure sure, I get in terms of efficiency. I have played a nova sorc, dual dream sorc, auradin, javazon ect in the past. I want to play stuff thats fun to play and dont care that much about efficiency. I was just wondering, in this specific case, whether there is an absolute gap between, say, a mavina bowazon vs a demon machine sorc - because they are entirely different beasts in the cash money department.
