Honestly, I want to do BLU content because I have nearly nothing to do until the expansion.
I'am lvl 50, got every spell before lvl 50. So, I have half of the spells.
But I don't want to wait in pf and struggle with RNG for getting the other half.
I don't want to to blue carnival (did only 1st mission) with half of the spells (130 potency everywhere not fun).

So, I'am blocked.

I have said it before, I was for how SE wanting to implement BLU in the game, but after one week to spam the same spells and seeing the promises not kept (solo & overpowered job), I changed my mind and changed of side.
You can keep the learning spells method in the overworld for special jobs like BLU, but I don't want any more limited job.

Implement BLU as a normal job (for 6.0). I know it's possible. Let's be creative SE !
