I tried being nice and it got me no where and frequently kicked despite never dying, pulling my weight, ect so now I have a fuck you attitude in LFR.

If I can roll need, I do it on all 5 regardless if I actually want that item or not. Enhance/Hunter loot? Something I already have? Thanks for the vendor gold!

I leave something to roll on for one of the toons to avoid getting kicked and make sure we're in combat once the timer is up. Do this for the entire raid.

If people do complain and manage to kick one of my shamans, I'll start the next encounter and cause a wipe. Then self res, mass res everyone and start the encounter immediately. If they're going to vote kick me for simply multiboxing, fuck them. I can usually wipe them 3-4 times before they get all 5 out of the raid.
