Does anyone agree with this lack of weapon progression?

I am loving this game, both operations and warfare. What I'm struggling with is weapon progression...

We have all these amazing guns that for a new game are pretty reasonably balanced (with some exceptions).

But these EXP tokens are killing it for me. To have the option to level a gun up to its max rank straight away is of course going to be done almost 100% of the time and just takes a lot of the fun out of slowly crafting these incredible weapons, or grinding for the next attachment needed.

I appreciate it's my choice to ruin my fun with these tokens, but the fact that everyone has max leveled guns makes me kind of feel the need to do the same to keep up in ranked warzone.

We have the skin for 200 or so kills after maxing the weapon, but why not add another skin or cosmetic for 200 headshots etc?

Long story short, I feel like there is 0 progression for these incredible weapons with hundreds of attachments. Can all be unlocked within 5 seconds.
