I have main tanked pretty much since the day I started to play this game. If they add blue mage as anything, I don't care what, I will switch to that immediately. I don't care what they have to do to get it into the game. My top concerns are: Will it have enemy or enemy like abilities? Will it have enemy attack names at the very least? Will the animations be more monstrous looking instead of casting, like doing things like spitting seeds? If those things are met, or even somewhat met, I will play blue day one and never anything else.
