we just about wiped in CM on 3rd boss because the warrior wanted to main tank . Ended up tanking boss with my paladin after warrior died and half the raid .

I died in ifrit HM on my warrior , I almost die everytime , but with my paladin I am god mode as tank in ifrit HM.

Also in 4 man dungeons I can stun multiple mobs to potentially save from wipe when something goes wrong . Cant do that on warrior , 1 stun that's it .
