edit:
why the fuck did i just thought this was a poll thread o_o
anyway
probably sniper or hwiz
both can kill high mvps for their loot. both can dispatch mobs (SS/SG), money making just depends on what you're killing . sniper is deadly in woe while hwiz is more freeze the shit out of everyone with SG
But srsly, at least at the part of money making. you can do it with every class. you just need to pick the place that char does it's best in kills/money gain per kill ratio
