Yoshi P talks about Warriors- from Producer Letter Live @ TGS

[Amyas]

I want to ask Yoshi what WAR is supposed to do for Titan HM then. Go as DPS just for that fight, since it's literally 10 million times easier to tank Titan HM as a PLD?

I tried to tank Titan HM as WAR today. I really did. I went in with Garuda's Scream, the AF+1 chest, and everything else DL except helmet. Mountain Buster was dropping 4.5k damage on me straight up and I have about 6.9k HP. How a healer is supposed to heal me through that with Cure II that does 1.3k healing on me is a mystery which no one has been able to solve..

I think that means you're not as good as you think you are with Warrior.
EDIT: 4.5k is nothing, in TWP I tell dps to go all out on adds when I tank the King, so far with full Rancor buffs he hits for around 4.8k as much as I've seen, always been able to recover with buffed inner beast and a good healer, in fact, that's the only way I've been able to beat the fight. With dps killing adds asap I mean, rather than holding back. And I didn't even stack vit.
