P90 is a beast but I don't think it needs a nerf. It's super forgiving and a can melt at close range but as a heavy, I still 1v1 against a p90 with a lewis even. It's certainly annoying when there are 3 p90s running heal though.
Bfr hits like a truck and people say it's satisfying but I think it's a little underwhelming. It feels too close to the medium revolver. Higher base damage but the headshots feel meh. I still enjoy it but not as fun as the med revolver.
Haven't played on new Monoco structures. Been getting a lot of Kyoto but it the changes to it are really nice. Flows quite well now and removing cashouts from the forest is a big plus.
Overall, this season felt like a lot of QoL updates. Wasn't a fan of the added delay on gadgets but that's been reverted luckily. It feels like they are preparing for Arc Raiders release.
