Re: You can't unequip something. Once it's equipped you can't remove it
Remove attachments should be a must.
I usually change between 2-3 classes(professionals) and 3-4 weapons for EACH game for different situations, and let me tell you that memorizing each scope, bullet and attachment for every situation makes me usually lose the capture or that tank that is killing all the infantry or the helicopter that is max distance camping that went too close.
Make it like you can add and remove attachments in the menu, and then in-game you can switch to them. This ain't a big deal to fix, but is a big life savior for players.
