I think that regardless of what you have as a main tank, each raid group should use a warrior as an offtank. Not because they are inferior (I have no clue as to if they are good/bad as main tanks, being a paladin and all), but because in single mob situations, from what I can tell, warriors can actually put out decent dps when out of tank stance. On my paladin I feel like I hit bosses like a wet noodle in sword oath when I'm not tanking. Outside of being a stunbot on hm ifrit, I think having at least one warrior in the raid will be hugely beneficial.
