Been slacking lately... But thought i'd add in what i've done,
Shannox heroic, not suprised, did it a while ago but deleted the footage, didn't reset once, took 40-55 stacks and just simply nuked him down.
Warlord Zon'ozz, wanted to try for ages but that claw pack that bugs prevented me trying, found a way to kill it and ended up 1 shotting zon'ozz doing 10-10-10-4(enrage was 20 secs away else i'd take more bounces), he died after 4 secs of enraging lol.
Stone guards... 20% i will get you >.>... have no luck with trinkets sadly, awaiting even the LFR versions of Zandalari/Feather.
