If you won't play without Blue mage.. why not just stay in 11? Y'know, since it's already there, fully functional etc. Isnt' that a better option then simply yelling DEAR FFXIV I WON'T TOUCH YOUR GAME WITHOUT BLUE MAGES.
It's the same as all the people saying "I won't play FFXIV unless [insert aspect of XI] is introduced!" If its's already in XI, why not just stick to that?
XIV isn't XI. Yes parts are similar and mildly nostalgic, but it isn't a clone and shouldn't be. Enjoy each for what it is. Play the one that has the things you want.
