This is pretty much useless, but definatley interesting.
If you are a priest and you are dueling somebody, and you also happen to have first aid, and some kind of bandages on you, you can mind control them and first aid them. this will break the mc, but the channeled spell will still be going, so you will heal them, and YOU will get the debuff, so if you need to heal them for whatever reason, mind control your opponent and first aid them. you can do it over and over since they don't get the debuff.
like i said, useless.
UNLESS: say your i a duel with a friend, and you guys pulled some mobs. you are going to win, but you dont want him to die, so you mc bandage him....
