Here's the info I've found out so far:
Races available: Barbarian, Ogre, Troll, Vah Shir, Dwarf
They're kinda like a cross between a monk and a warrior. They have INSANE damage dealing capabilities, at a cost to AC. They get 'berserker modes' that do special abilities, usually to increase dmg, and lower AC.
They get special abilities pertaining to throwing skill, too. I've heard many rumors, but SOE has only confirmed the existance of the abilities that I've seen. But I've heard that one of them is a snare built into a throw (maybe they throw the dagger into the leg or something, I dunno). Dmg bonuses to throwing wouldn't be too hard for me to believe either.
Only confirmed weapons that they've said they can use are 2hs axes. SOE justified this as the sheer fear factor of them. I'm assuming that only 2h weapons are weildable. I hope this helps.
