I don't mind if they keep BLU within this scope of Limited Job... I find it fun, actually.
What I do mind is if they once more overlook the fact that BLU is not a truly solo experience. We need people running dungeons to be able to form parties. In the occasion of BLU remaining as it is, they need to figure out a way to inject more activity, and the only way I can see this happening is to having really attractive rewards for the daily and weekly dungeon/trial marks.
And another thing they really need to do is to move the essential spells and Job quest objectives OUT of group content, so people won't hit a wall while leveling due to the lack of players running the dungeons.
