Everyone has been doing the sunwell trash farming pugs, so how to profit from it? Usually the raid is always on master looter and everyone rolls on the items afterwards.
So you need to change your emote color to yellow with a hack and then:
/emote rolls 100 (1-100)
Everyone else sees you as rolling 100. Save it for the sunmotes and big recipes.
I saw a raid leader do this 5 times in a row yesterday, and finally someone got angry and pulled some mobs for a wipe. Then the raid group disbanded.
Don't over do it. Let other people win some stuff too, so it doesn't look like you are cheating.
For all you people who say it is impossible to hack the /roll, lolz to you. You don't need to hack it, just spoof it.
