Because we're the only faction with the numbers to actually tank the numbers of deaths we've lost in game thus far.
I'd love to see something for him but i doubt it would be anything totally "unique" as in only he can use it. I got some flavor text with the ork's white pants so he can definitely be hinted at somehow in the game.
He could get his own name tag or buttons on his orky shirt saying My name is Thrakka and have a orky smiley face beside it
What i would like(wich is the least likely thing to happen) is if his model becomes the actual warboss of arkhona, that tea drinker is not my warboss!
Its possible. I mean just look at Warcraft for example. How they made that one red shirt fan into a NPC and of course Leeroy Jenkins. I'd Thrakka could make for more worthy Warboss.
