Original CANCELLED WoW Expansion! Ogres Playable, Pirates! By Doronsmovies
I wonder what else was on the table back in the day.
Ogres/Two-Headed Ogres would definitely be a surefire fit for Horde and always should have been playable. I really hope Turtle WoW develops them and puts them into the game as they were intended.
Pandaren could fit fine on Alliance, their Brewmasters would so easily integrate alongside Dwarves.
