Orgash is your typical brute, just charges in with relentless fury and overpowers his foes with brute force. Imagine Garrosh, only to a slightly lesser extent. It's hard to implement this IC, but the way I write him is that he's an orc that's bigger in build than most, like he towers above others. His physical strength is also fairly impressive, he's like the orc equivalent of the hulk, but other than that the only particular thing about how he fights is that he's very primal. He has very strong senses of hearing and smell.
I had a dwarf hunter, Midar, whose fighting style was more interesting. He was very hot-tempered so he'd just rush into the frontlines, fight with axes and and breathe out dragonbreath chilli, then he'd run back to a safe distance, shoot a few rounds then run back into melee.
