If you’re raiding, you’re probably going to want a warrior tank. Druids and Paladins just didn’t have the full tool kit they needed to be “real” tanks yet, though they came closer than anyone else (sorry Shaman).
As I recall, Druids, Paladins, and Shaman all pretty much ended up in healing specs if they ever wanted to see the inside of a raid. Could be wrong, though, I didn’t do much raiding in Vanilla (and I wouldn’t have known anything about raid comp even if I did).
In raids horde druids don’t get benefit from Windfury, and alliance druids get 10% all stats from paladins’ Blessing of Kings. I’m wondering if this difference is sufficient to make a real difference.
(I’m not interested in playing warrior, and shadowmeld isn’t usable in combat in Classic.)
Druids can get chain bubbled by a disc priest and still get rage, unlike a warrior, a little fact overlooked. A disc priest also wont run out of mana healing a druid who has more health than a warrior tank.
Is it super optimal? No. But if you build around it, you can make it better.
Druid tanks are viable in all 5 man content, and while they wont ever be straight up better than Warriors, they 100% can tank in most of the raids on most of the bosses, as long as that druid itemizes correctly and knows how to play their class.
This goes for (almost squints at boomkins) all classes and specs
Yes, I’m a huge fan of Skarm ! As well as a highly knowledgeable tank he seems like a genuinely nice bloke. He druids as alliance, and I can’t recall him mentioning horde bear tanking.
