Weapon camos locked attachments?!

Okay i am going to be real. I was hyped to finally get my first weapon to presige and now i do not even care to presige another one. You can not tell me EA intentionally made its own attachments to be LOCKED in with the certain camos and when you put your own attachments in it resets back to its locked attachments to the camo when starting a new game?!? That is beyond ridiculous. Like i said, everyone plays different and wants different attachments to put with there camos. COMPLETELY IRRITATED, SO ARE OTHER PEOPLE WITH THE CAMOS/PRESTIGE. Makes zero sense at all. Its like a slap in the face!
