Tbh SE added BLU as a piece of solo content because in my opinion that's one of the things that this game lacks.

If you look at BLU as solo content then I think they did an alright job.
But if you look at it from a job standpoint, it's very disappointing.

I'd personally love to see more solo content added to the game but i'd much rather see BLU become a proper job rather than it being a solo thing.

BLU as it is in the game right now just isn't even a job.
