[Suggestion] Weapon-class specific two-for-one attachments

Every primary class weapon (SMG, AR, etc.) would get three weapon attachments which only cost half a point - allowing two of them to be used for only one class point. These attachments would be the most 'clutch' attachments - allowing more diversity in gun customization. Obviously this would also force weird builds, with more choices. It would also lead to a very different meta, probably with more lethal / tactical use.

These are my opinions for clutch half-point attachments:

SMG: Silencer, Fast Mags, extended mags.

AR: Long Barrel, High Caliber, stock

Sniper: Silencer, FMJ, ?thermal?

Shotguns: extended mags, fast mags, stock

LMG: ?thermal?, extended mags, fmj?

I'm really high, let's discuss things that aren't cod points!
