I'd like a heavy weapon maiming DPS, maybe using hammers or something, but not sure on the flavour for it or what classic job to base it on.
Either way, i thought of a 'ramping up' combo system that can be used, sort on like monk stances ctossed with dark arts, whereby repeating certain skills built up 'momentum' and increased the potency of their finishers based on how many times you used the pre-finisher moves.
