Wow I went in there expecting I'll be doing the Emperor atleast a few times but I died only once (missed the instadeath cast interrupt). I used no tricks and my T7 was in lvl 14 gear and died instantly. I was watchman specced so I had lower cooldown on interrupt, I just interrupted everything he threw at me, especially the long cast and when the adds spawned I just used the basic attack on them. Not that hard really, just gotta do your interrupts I guess.
