ICC Festergut encounter - Prot warrior tanking, help!
So my guild just started up a 10 man ICC raid, I'm the GM and a DK Tank (Soulstorm - Blackhand (US)) and have been leading our raids, my OT is a prot warrior (Tinetti - Blackhand (US)), everything is smooth, we one shot everything up untill Festergut... my prot warrior just can't seem to handle him.
I tank it first, get up to 9 stacks easy, and have him taunt off, he's already got hots and heals on him as he taunts off, but he takes huge damage, and face plants after one or two stacks... I can usually figure out our problems and correct them fast but this one has me stumped. Why is he going down so fast? He's got 5k+ GS, he's def capped, has a decent tank spec... I'm at a loss, anyone else have this problem? or know what's wrong? Ideas? Im desperate.
