Tried some of SSC Bosses as Fury (raidgeared, some 372):
Hydross the Unstable: was not doable for me without resistance gear. With stacked debuff he critted for as high as 25K frost damage. Self heal was not enough. Never got him below 1 Mio. Tried preventign the stacking debuff by making him change frost <-> nature. Adds were not a problem. But it did not help. Should be doable with frost gear though.
Lurker below: did it on the 3rd try. Had to enter his pool though with my back to ring so I could not get kicked. Being kicked results in a lot of elementary damage and less self heal. Intercepts did not work reliably. Had to do the add phase once. The ranged on three different platforms can be a problem as you have some considerable travel time.
Leotheras the blind: Didn't kill him but should be doable. The lowest I got him was 80K and 45K. This was witout any fire gear. Should be easy with some fire resistance gear, as his demon form is the only challenge on this encounter. Even blowing all cooldowns (deathwish + recklessness, resistance TB trinket and SW at the end) the debuffs stacked so high that his bolt damaged me up to 35K at the end.
Morogrim Tidewalker: Could be doable as prot. As fury the lowest I got him was something around 50%. Not even in kill range. Gave up.
Karathress and Lady Vashji I dit not try. Vashji should be eimpossible though because of the mechanics.
@some previous poster: Sartharion (10man) adds and trash is doable as fury, but quite challanging. Not that one add with immunity though.
Voidreaver (TK): I could not kill him as fury. The elemental orb attack really hurts. As some have stated could be doable with some tank gear though.
Maulgar Council (Gruul preboss): Tried him 2 months ago as fury (when recklessness were 3 gearenteed crits still). Killed 2 of his adds (warlock and priest), my HP was still at 50% with enraged regeneration and SW still up. But the mage does really hurt because of the damage + constant sheeping. Gave up. Given some gear upgrades + mastery buffs + recklessness change he should be burstable in the near future though. I reckon he should be doable if 3 adds die as soon as possible: priest, warlock, mage.
