1) Your orc shaman character is a minor villain from the comic and not Thrall? The hell, Blizzard?
2) Stop trying to make it look as if Rehgar is/was a gladiator. Rehgar is a slavemaster. He didn’t fight in the arena: he bought and abducted people and forced them to fight to the death in the arena, against their will, for his own profit. Rehgar is an evil scumbag; the primary difference between Rehgar Earthfury and Aedelas Blackmoore is skin colour! But I guess that makes all the difference, right?
