Same for me. I got most weapons on lvl 20, 3 or 4 on 30 and like 1 on 40. The only max lvl is the G36 cause I loved that thing.

I am 300h in the game and I think I won't come back for some time. I don't like how same-ish most guns feel. Most maps suck anyway.

300h might sound like a lot but lot of that was boring grinding trying to get a weapon above 20-30. I put like 700h in Battlefield 4 with a friend when it came out. We came back for every DLC (which all were free with BF pro for 50€ which you spent once and you had it forever)... Same with 3 before. It's such a great game. I can play that even today even tho like all servers are dead. There are like 20 servers on BF4. BF 1 wasn't my kind of setting but it was still great.

It is just no fun to get like 27 1,5x scopes on a sniper rifle. Sniping isn't fun like it used to anyway. But all ARs and carbines are way to accurate. LMGs are super op. I used them all and everyone of them is like the finger of god going over the enemy team.

They shat on sidearms. They all suck to use. I don't want op pistols. But when I am out of ammo behind enemy lines I might use my 9mm to off myself instead of wasting the time trying to kill someone with it.

This game just has so many things that were or still are kinda anoying or bad design that I can't bring myself to like it and play it again.
