I'm very disappointed. I enjoy playing solo 98% of the time, and thought that BLU would cater to this even if it was excluded from the majority of activities in the game that I enjoy (e.g., MSQ). But locking the majority of spells behind instances---and not even allowing BLU to use his or her squadron to complete them---is hardly something that makes this a good fit for solo-focused players. Looks like the limited amount of time I have to invest in this game is better spent on getting tomes for my main job, so I've already abandoned BLU as a (for me) useless experiment.

EDIT: I should hasten to add that I don't want to take anything away from the people who ARE enjoying the job. I think that, for some portion of the community, BLU is/is going to add a great deal of enjoyment to the game. For me, though, it's not content that suits my playstyle.
