Your reasonings on tanking Sathrovarr seem right, but he's VERY tankable. I've been MT'ing on my warrior all last night and tonight since my pally hasn't made it to PvE yet. Between myself, another prot warrior and a bear we hold him probably 70% of the fight once the first portal is out. He certainly hits hard, but nothing 3 healers can't deal with, a word to the wise though, wait to taunt until Kalecgos has just taken the knockdown + 8k shadow nuke and it will save you a big burst on your opener.
Haven't yet killed him but we got Sathrovarr banished and Kalecgos(Dragon) to 4% in a heartbreaking wipe. We'll have him tomorrow.
Just to throw this out there,
http://armory.worldofwarcraft.com/character-sheet.xml?r=Turalyon&n=Davia my warrior. Paladin is missing 1 item realistically, shoulders, to be on par with gear and I've been MT'ing Kalecgos in full stam gear so my pally would obviously win that race. Shouldn't be an issue for any t6 tank to holy Sathrovarr at all.
