Now, you may be asking, what does "Worgen-type" mean? Basically, it means a playable race that can fill these three criteria:
1: Have their true form be bestial.
2: Have the ability to shift between their true form and their humanoid form out of combat.
3: Have the ability to be their own mount.
One of my ideas is a Troll tribe that gain the power to switch to a humanoid Raptor-like form (unrelated to the Zandalari "Moonkin" form)
And no, Dracthyr don't count because they are restricted to Evoker.
