I haven't played BLU much since completing the Masked Carnivale. I occasionally toy with the idea of going back and trying for the special BLU achievements, but I have so much else to do that it continues to fall by the wayside. That said, I DID genuinely enjoy the puzzle-fights presented by the Carnivale; I only "cheated" and looked up the solution to a fight once (and it was such an obvious and easy solution that I felt bad for doing so).

I've definitely not played BLU as much as I would have had it been a regular job. I level every job to max, and BLU in particular would have been a strong contender for becoming my "main" DPS job (a position currently held by SMN).

I definitely feel that BLU is not living up to it's potential, and I dislike the concept of "limited" jobs in general. As much as I'd like to see BLU changed into a regular job I have little hope of ever seeing that happen; there are some fundamental things about the way it was implemented that simply would not work as a regular job, meaning it would pretty much have to be redeveloped from the ground up. That presents some serious obstacles in terms of money, manpower, and PRIDE - the last because it would entail admitting that they were wrong to implement BLU in this fashion.

I do occasionally still see BLU parties in party finder, and when I run Ex Primals for WT I usually leave slots open for BLUs to join and one or two often do.

I do believe that we would have eventually gotten BLU as a real job, had it not been added as a limited one. It's simply too popular for the Devs to ignore it forever. Unfortunately, we wound up getting the "here's your blu now shut up" version, which saddens me greatly.
