I finished questing in Deepholm yesterday. I found an Earthen NPC who called the Stone Troggs “a mistake of the Titans,” which, yeah, they are. The Titans created them, but were disappointed by the savage beast race they had created. Even most of the other monster races aren’t considered a mistake, besides the Kalimdor Centaur.
I would like some development for Stone Troggs and Troggs besides being savage brutes. Mayhe have them find Kaja’mite and become friendly.
Troggs in Hearthstone have sort of an anti-magic theme, gaining power when your opponent casts a spell. Troggs in WoW could be helpful with this.
