Premium warbond weapons and progression

I really wish they would put levels on these weapons. I get that we cannot add attachments or camos to them, but please. I really like mastering a weapon.

In Call of doody games it was maxing out the weapon and it felt like progression or something to work for.

Since these weapons don’t have any levels I don’t see a point to use them past the trying them out.

Let me know your thoughts,

Thank you,
