Its a bit embarrasing - but I got beaten by Chromaggus in BWL :-/ I never knew, but it seems that if a toon get all the different debuffs at the same time, he/she/it will turn into a dragonkin and help Chromaggus. I've killed him 2 times without noticing this, but the last 2 times my poor toons have turned into dragonkin.

So, is it possible to make a macro that cycles thorugh all party members and cast dispel/remove curse on each?
