I hate being a "Wet Blanket" but I get so tired of cancelling off Jack O'Lanterns months after Halloween and still get "Mohawked" all the time.
This small AddOn is for those who are tired of cancelling these buffs. I have started with the two that I find most annoying (as mentioned above) but I it can be expanded to include others.
Current "Buffs" that this removes:
Mohawk!
Jack O'Lantern!
*special thanks to Tekkub for cleaning up my code and to Khavatari who gave me the idea with AntiMohawk.
