Granted, its been a while since I played anything D&D orientated, but I feel the "charm person" mechanic is wrong (Unless it changed in 5Ed?). I charmed a creature but it still attacked other members of my party. Ok, it didn't attack the charmer, but seriously what's the point of that?
Last time I remember when you charm a creature it fights with you (Party included) against your enemies, not you friends LOL!
I have been disappointed by it. I turned into a drow, unstoned a drow, charmed her, and she attacked me. Wtf. Pure scripted social interactions that I can tell. :\
