I think it would be cool if SE were to add another job mid-way through the expansion, like they did for NIN. If they did I think it would be cool if it started as a class at level 1, then branched off into two BLU variants at 30: One is a tank, while the other is a healer/controller that's buff/debuff focused.
I know this is super unlikely to actually happen, but it's a class I would certainly enjoy leveling up from 1.
