The content difficulty is arguable, but it's fine.
The real issue is the way it was introduced still makes me wonder who exactly it was meant for?

The lack of premade/queueing to it and having the free for all "just go there to join" system makes it seem like it wants to appeal to casuals who want to "try it out" when it pops, but the amount of personal responsibility and coordination in both jobs and mechanics required makes it seems like it's meant strictly for statics.

I'd love to read the design doc of FTB just to see how it was presented and argued.
