MCPoly basically does two things.. It scans the entire raid to see if someone is being mindcontrolled and if so, it will start polymorphing the raidmember. All you have to do is assign a keybinding. MCPoly will also skip targets that are already polymorphed or out of range.

I made this addon in a hurry so i've only included polymorph rank 4. I might work on this addon a little more in the future, but for now, have fun..

Note: when you are not in a raid or none of your raidmembers is being mindcontrolled, nothing will happen :P
