Warrior is OP

[reality_check]

The reality is when I'm healing a warrior my Stoneskin is just as efficient as cure II. This completely changes my play style as to when I'm healing a paladin and Stoneskin is a complete waste of MP.

That's the problem with you bandwagon crowd. You can't defend something with numbers on paper when the game is so much more dynamic than that.

Here's an actual situation of what happened with a warrior tank and a paladin tank who didn't know the Titan fight that well.
Both paladin and warrior took two bursts by incorrectly placing themselves between bombs and getting hit by both. Both of them ended up at a tiny fraction of their health. The warrior popped last stand and the paladin popped sentinel. Who do you think survived the incoming auto attack? Sure, you could argue that the Paladin could have popped sentinel before the bombs and survived better but we don't play FFXIV on paper.

Also, do you know what are infinitely more useful to a tank than conjurer cross class abilities? Pugilist ones.
