Yea you either like Cait or you don't but there's a few other fully female companions (if that's what you want) that you can get and ignore Cait till she's needed for her quest eventually.
I dislike Cait not because she won't remain "loyal" to my pc but because she...usually takes the spotlight away from female pcs on loss/submit scenes. My char is left feeling like a fresh, steaming turd while everyone fawns over Cait and who gets to fuck her first. So that bitch can stay at home. T.T
Also I'm extra bitter because the Minotaur area is the one I'm looking forward to the most but a few months ago I saw this:
That's MY pc's job, god damnit. I just hope Wsan comes through and there are some nice Brint-involved scenes available at the very least.
