Hear me out. Just a lil bit of fun. Tauren, Worgen and Nelves all have a bird flight form (Eagle, Crow and Storm crow respectively). But trolls have Bat form.
The first 3 races have fat bird bear caster forms AKA Moonkin. So I find it kinda odd that trolls have a Gallah/Parrot themed moonkin form.
How'd you feel if they instead had a slightly remodelled Gargoyle form instead? I think it'd be kinda neat.
PS. Writing this in a hurry because I was going to post it last night, but I decided not to, but now I'm posting it today, and I gotta go out for an Hour, so I won't be able to discuss or explain further. Sorry folks.
