I agree that not all humaniod races should be designed or have a design for PC use, but Races that have been in the past should be.
The Minotaur has too much D&D history to reinvent the wheel.
The cursed or mutant verison should be seperate from actual Minotaur race, he should have a name and be much more powerful.
Just a thought, but we already have that being it just occurred to me. Baphomet himself is The Minotaur himself, he's already damned, lives in a deadly Labyrinth, huge and powerful, and beastial. Any cursed mortals would merely,be his reflection.
The frees up the Minotaurs as a PC race.
I'd like to see Yikea, Labyrinthian, and Kothian subraces of Minotaur. Yikea would be Al-Qadim Yak people leaning towards evil, Labyrinthians would be the 4e Minotaur, and Kothians would be the sailing Dragonlance verison.
Alternately THE MINOTAUR could be a semi independant aspect of Baphomet's nature, like a more pure manifestation of his nature that,possesses some poor unfortunate soul until iy,dies and then finds a new host.
