I just thought of this..
Okay, your in a raid. Lets say MC.
Brutality Blade drops. Your a rogue, but your raid leaders gay and giving warriors the first choice. You pretty much know who is gonna get it because DKP is pretty straight forward. Lets say "Drachen" is gonna get it. And let's also say your name is afi.
Before the raid leader gives it yo Drachen, whisper your raid leader and say this:
'Oh man, i really want that, you sure only warriors can get? <Spaces here untill you cannot see what you just typed> [Drachen] whispers: Hey man, I dont want it and AFI is a good pal of mine, please let him spend the DKP on it instead of me, he needs it.'
Or something along those lines.
It should look like this to your raid leader..
[Afi] whispers: Oh man, i really want that, you sure only warriors can get?
[Drachen] whispers: Give it to afi blah blah.
--note-- This will prolly get you the G kick, but you may get something nice out of it . After you get the item, the person you impersonated will be like "ZOMG WTF i have m0re D33 K4y P33!!"
Enjoy
