So I just finished the raid and a guildie put some script on the guild chat, I used it and imagine my surprise when I saw it was the Cataclysm spell that warlocks had on the PTR :O
It looks awesome and I'm sad it didn't make it to live, when I remove Mannoroths Fury it stopped working though. Anyway I wanted to report it because there may be many exploits related to it. I dind't do any dungeons or pvp with it, but I can imagine it being specially OP in pvp because it has a pretty big area.
The script was /script Pickup Spell(*some number*)
(sorry for the crappy english)
