I'll give a go at trying to explain a way to ninja in a raid if you want an item that you know a few others want as well. If many people wants it, it's much tougher to make it work tho.
The trick here is getting raidleader to make you assist in the beginning of the raid for "inving" some1 or marking.. whatever.. your choice..
And right before the bossfight for the boss you want a drop from starts, you type >> /kick raid3 << if the member you wanna kick out of lootdistribution table is nr 3 in the raid.. just replace with 24 if the member is nr 24 in the raid etc..
The raid will normally go "wtf?" and inv him back quick and the boss will still go down ^_^ and your "opponent" in lootdistribution will be out of the looting table.
And an important fact to this trick is that it can't be traced to you.
On the kicked members screen it will show up as "You've left the group."
And for the raid it shows up as:
"XXX has left the raid group"
"XXX says: wtf? inv!"
I'll gladly edit with credit if some1 else have posted it before me, but I couldn't find anything so I'll give it a go myself.
