I mean, at implementation the only story stuff that would have been accessible to BLU would have been content available from 2.1 through maybe bits of early Heavensward, level-wise. You can't unlock it until you complete the 2.0 story anyway. I'm not sure why that's so surprising? If you're concerned about how this affects the job in the future, once the level cap eventually increases, well it remains to be seen how they will handle it then. After all, as much as the devs may try to imply it sometimes, nothing's set in stone. Heck, BLU being playable in the first place is an example of that. For now, it is what it is, but I still don't plan on solidifying an opinion until we can actually play the job and we have a chance to actively see how things work. After which, I'm sure I'll have feedback of my own on how BLU should, imo, be tweaked in the future.
