Trolling purposes aside, it was a very good raid-recovering spell.
Also a very good way to stop that overzealous healer from healing when raid leader called a wipe.
Sadly, Blizzard removed it in Cataclysm, and it doesn't look like they want to give it back.
Could anyone with access to US beta forums post a topic there calling to give it back ? We had one on EU forums for quite some time, yet it seems like it was completely ignored by blues.
But please, if anyone is going to make a topic there about it, use above reasons. Not the trolling purposes, it won't help to bring back that wonderful spell.
