The thing I see with all these arguments is everyone seems to make a case for level 50 BLUs. Which I suppose everyone will agree is underwhelming.

But BLU is still very OP. At low levels. Once you pass the point where 1000 Needles is doing all the heavy lifting, then you start getting a better feel for what the job is actually capable of. Up until then, let nothing stand in your way.

I'd wager it's one of the biggest factors to the job being prohibited from queuing for duties. Between that (and arguably MG and WW), and nothing being tied to level so not losing anything when synced down, it's a job that is very much stronger than all its peers. At low levels.
