Heyo there,
I can recommend Hand of Zul if you’d be interested in a troll-only supremacist RP. We are basically following the vision of Prophet Zul(before he decided to dabble in the Old Gods stuff, of course) who wanted a united troll empire just like in the ancient times, to rule all of Azeroth!
We accept all tribes(apart from blood trolls) and do not align ourselves with either Horde or Alliance. If this would interest you, then have a look at our forum post
