That's ok balancing the games main mechanics is the main priority. I am merely suggesting ideas you have to think about how to implement them or how they would effect the game. Just one more thought then rather then having it be a main mechanic or gimmick. Have it be that if you taunt behind an enemy before you stealth kill them you get more magic meter. Maybe with an element of it you are seen you lose some.
I realize that you main focus now is in the development of levels so you may as well concentrate on that for the moment. Glad to here you got some good feed back.
