Let's not be too hard on SE about BLU and in general.

The thing is, it's locked at lvl 50. Why play BLU in the lvl 50 overworld when your lvl 70 characters can kill everything in one or two hits. Why go lvl 50 BLU in PF duties when most people unsync them in. BLU may be fun to play and collect abilities on, but once you have, it's almost useless. That's my gripe with it.
