People who are mad about the "limited job" didn't actually want Blue Mage.

What's with this idea that BLU is about having overpowered and broken skills. It's about using monster skills and casting them as blue magic. Not all of them are broken and unbalanced and the class can play like a normal one in its history. Just because a few games had fun and gimmicky stuff doesn't mean that was ALL the class was built for. What is this nonsense even?

But how do you balance 'gimmicky' stuff in a dungeon, then in a raid environment? In dungeons, you can apply most 'gimmicky' abilities without trouble, making them borderline overpowered (think of morbol breath here). And by raid bosses, those wouldn't work most of the time due how they are close to be immune to everything, making them useless. Or even vice versa.

You can't strike a balance with the Blue Mage here in FFXIV unless they fundamentally change how abilities work in the game.
And that's something they aren't ready to make for a single job.
