Have to learn? Useless shit? I don’t quite get your point, it’s not like allowing blutsauger is our way to confuse the newbies again?

I see the unlock list as allowing a select few unlocks which improve the game rather than banning overpowered unlocks. The unlocks allowed are either cosmetic or are carefully considered to be good for competitive play, so why allow a useless weapon? It just seems unnecessary.
Yes I realise it’s a small thing, but would if the blutsauger was released now, would it be automatically be allowed because it’s bad? There are no other unlocks which are allowed which are bad
