having completely different fighting style.. i don't think so, they just make it that you dont think too much about rotation and can focus more on how the flow of the pvp going (taking control of the flags/planning attacks). you still have combos and stuff related to your jobs, and at most they just add some pvp action but that's it. however i agree about how blue mage can easily be intregated in the pvp scene, like a caster with gap closer as its unique trait (j-kick) or kamikaze with final sting. it might sounds cheesy but you need to know when you can use it and when you can't. maybe set the timer to a high amount etc.
