Mr. T hacked the game and put in a Night Elf mohawk of his own, but will we be able to do the same with the next expansion? Could be-- Bornakk says that he hopes every class gets a mohawk to choose from when the new hairstyles come down in Wrath of the Lich King, but the actual model from the commercial was custom-made for Mr. T.
A mohawk might not be your first choice, but it will be nice to have some new customization choices out there-- I was showing off all of my alts to a friend the other day, and it occurred to me that I must have created an alt for almost every look out there. Not every combination of looks, surely (there's got to be tons of those), but at least every look that appealed to me. Just like many players, I'm definitely ready for new looks, whether they look like Mr. T or not-- if we've got the mohawk coming, does that mean we'll get a mullet for Blood Elves?
