Plasma shield. Sometimes it backfires and gives everyone a 100% chance to crit you, but when it doesn't it's awesome. 18k shield is great combined with combat readiness. It also lets you stay in stealth when you're dotted since it absorbing damage doesn't break stealth.
Cardboard Assassin seems to be the way to go. It's an emergency button for dealing with a loose mob, but it does that job well.
The Grounded Plasma Shield *should* be a good option, it saves a fat chunk of damage, which your healers will thank you for, but if it goes wrong it could wipe the raid (the AOE taunt backfire is pretty brutal).
Well, judging by your responses I can tell that cardboard assassin is the way to go on raid/heroics (plasma shield may have a 5% chance of failing, but if it fails I will probably wipe the raid and get Gkicked, so it's not worth the risk).
Now for BGs, world pvp and grinding, plasma shield sounds nice to stop DOTs, nitro bosts are still good (if the "kill you" side effect doesn't happen often).....
But what about mind amplification dish? I heard there is a way to actualy move the mind controled person, but for how long? Enough to throw them in a pack of mobs or make him jump off a cliff?
