I assume we're going back to the BC or vanilla model of tanking where at least one CC ability will be needed per pull and probably more, and the dps never unloads aoe with both barrels on elites because if they did, they'd die and everyone else would laugh.

I was feral in BC. Tanked Shattered Halls. There were half a dozen pulls with five elite mobs and a few pulls with even more. The pull would start off with a polymorph and/or freezing trap and/or succubus seduction and/or mind control (can't have sap; mobs in these groups could see stealth), but two such abilities at the very least, and then I'd Hurricane to get aggro on the three uncontrolled mobs. Obviously, that had to be timed just right. I'd have to duck around a corner to line of sight them from me because some of them would attack or cast spells from range. Then I'd shift to bear and tab-target from mob to mob to spread lacerate around, swiping all the while. Dps might be a little slow because everyone has to refresh their CC abilities.

That's one pull. Out of more than half a dozen. Paladin tanks had it easier, but I gather it was basically the same for warriors as for feral druids.

tl;dr version: When I was your age, I had to walk three miles to school, uphill both ways! In a foot of snow!

Well, after the Cataclysm it seems that you'll get to see what it's like. Remember your winter boots.
