What happened to closed weapon conquest?

Like the title says.

I’m a classic battlefield player. Joined back in BFBC2 and BF3. Started again in Bf6 because it looked like a throwback to the classic play style but now I can’t find closed weapon conquest anywhere in the menu and the servers have no players on them. What is happening?

I really don’t want to play cod style battlefield where I can put any gadget and weapon combo on any class. Just looking for a classic battlefield experience.

Any tips to point me what I’m looking for will help.
