I, for one, LOVE the bat form. Sure, it's ugly as sin. But so are trolls. What do you haters expect...Something pink and fuzzy? Trolls are pretty well enough known for having garish colors and crazy hairstyles - Naturally, that would carry over to their druid forms. For those complaining about the hair..Well, my Tauren doesn't have horns that look like the bear ones. Am I complaining? Nope.
Trolls aren't made to be cute. Neither are their forms. I'm still seriously considering race-changing to troll
