In case you were living under a rock for the past few days, one of the biggest announcements to come out of BlizzCon was that everyone who purchases Warlords of Draenor will be able to boost one character to level 90 instantly. There are no restrictions -- you can even use this on a fresh level 1 character.
After taking a gander at the newly revamped character models, I am pretty settled on using my boost with a level 1 female dwarf warlock. The new model they showed looks great, and it's such a unique class/race combination that I can't even remember seeing one before. I've already reserved her name and she's sitting in Dun Morogh, patiently awaiting the expansion.
Have you decided who you'll be boosting to level 90?
