Challenges and weapon/class leveling is a joke

Title says it all

Ive been playing quite a bit since launch but barely scratched the surface for one or two guns!

This is killing the game for me to be honest, I dont mind stupid goals for skins but not weapons, gadgets and attachments. Level **bleep**ing 30 for 10x scope?!

Its clear these challenges are either AI or someone who never played this game. Also, please have someone check the spelling, grammar and syntax of them because theyre so incredibly bad.
