What job is the highest priority to fix?

[Enla]

BLU is too overpowered:

1.) It has spells that are rng and never land in a game that focuses on killing trash by gathering them up and burning them down.
2.) It has White Wind which would ruin your DPS, eat your MP, and probably wouldn't be able to save the party if your HP is already low.
3.) It has a tank stance that lets it live for one more hit while lowering their DPS by 70% that's so horribly overpower think of all the tanks that will lose their raid positions.
4.) It has a majority of 120 potency spells making it almost on par with a scholar ruin spell, I guess.
5.) Oh and the primal spells, they are grossly overpowered acting like a BLM fire I at best and having a cooldown of 60-90s.

/sarcasm

seriously why was this job limited in the first place...

Probably because of the way BLU traditionally picks up spells, they wouldn't want someone queueing with it with only one spell for example, and the whole 'Death' spell simply existing to be frank. What I don't understand is why they didn't just omit said Death spell and lock BLU from joining any roulette's until it picks up a certain number of spells? That practically solves the issue right then and there. That or lock the more meme spells to map exploration only. There were a lot of ways they could have made it viable.
