Actually i think stamina is just the manual mechanic version of our Auto-Attack feature we have in ffxi. Since the game was designed to be manual input oriented, you have to have some kind of limit to your actions.
Now with that said, I will agree that I think MP should not be tied into the stamina bar, but the stamina bar should still exist. I only say that, because MP is already on a cast timer, it makes hardly any since to have MP on 2 separate timers.
I wouldn't even mind if they dumped the MP cast timer, for the already existent stamina timer. At-least it would make since with the rest of the battle system.
