4 bears + Shaman

Watching this video I made almost makes we want to reactivate and finish this team. The shaman healing looked insanely OP:

had to mute the music, sorry!

I wonder how well this scales. I tried 4 bears plus healer shortly after MoP went live and with the changes to bear power coming from taking damage, the other 3 bears didn't really do much. It was fun blowing up lots of stuff in non-heroics but heroics were an entirely different proposition. Just my experience from a while ago. Might no longer apply. ;)

Tanks rely on vengeance to deal good dmg, and you build up vengeance by taking dmg (before mitigation). Vengeance lasts 20s ... so you would need a 5s taunt rotation to benefit from it. The problem however is that as a tank you don't take every 5seconds a big hit.

The only reasons that I can see why you would want to run 4 tanks is because you either ...
... want easymode and not care about the time it takes to kill. You can avoid a lot of fightmechanics/brute force stuff with running 4 tanks, since they have the best survivability in the game
... for lols.

There can definitely be a benefit to run with 4 tanks, since you can game the vengeance. But there is no way that you can keep rotating vengeance with 4 tanks, besides maybe a handful of gimmick bosses.

At this state in the patch and with the equipment available you can easily brute force a lot of things with pure dps. Bosses in heroics last like 30 secs max now, unless they have a phases.
