I'm slow to vote here o_O
So ok, Magus was a cool bad guy and everything, sure. I didn't ever think much of bad guys, especially not main ones, save a select few, and he wasn't anything special, just a supposed main one until proven wrong. Suddenly he whips off the robe and turns out to be the Prophet. "Holy shit! That's awesome! Is he good now? I WANT HIM IN MY PARTY!!!"
And sure enough...
