Imagine xavius being able to 1v1 the person who imparts your classes power. They aren't powerful enough to bestow that kind of power, I think. Champions of Azeroth kill dragons every day, too. Playing a dragon wouldn't be OP, they are pretty average these days, and its a cool niche that is well-treaded in the Warcraft universe that has enough uniqueness to merit a class.
