Well to do any harder and more difficult NPCs(IE: Ring of Blood) you'll need two tanks.
We just did a Raging Colossus in outlands and it was only a 3 man. It was a piece of cake with a Disc Priest's bubbles. We could easily two heal Ring of Blood in a 10 man.
Two Prot Warriors
1 Rshaman
1 Dpriest
and 6 DPS(as many hunters as possible obviously)
Also: If you aren't willing to faction to NE, then go with this setup:
The only problem with paladins is, they cant get CTC capped. Meaning when we are fighting level 66+ Elites that can hit for 600-1000 DMG, you will simply just die if you dont block/parry/dodge every hit.
But I've never seen one in action, so you could always try this setup: chardev 9
edit: Just realized that paladins dont get righteous fury until lvl 12. It won't work.
It really depends. I've read the new changes and I do not think it'll be possible to even reach CTC capped as a prot warrior in MoP because they are getting rid of the extra block from going Prot @lvl 10.
For all I know, bear tanks will be better than prot warriors in MoP.
We'd be happy to have you if you did! Your gear is exactly what I'm looking for. Our guild will completely fund all your enchantments, supply rum, and even supply some of your BoEs.
