-cheating still exists
-biggest thing, at least for me, big performance issues such as with scoping and molotovs. not limited to that though, micro stutters are quite frequent in random/general play.
-missing console commands that used to be there
-maps removed
-movement feels off for me. personal issue though? just doesn't feel as smooth in general.
-seems like something is off with the netcode or something. desync perhaps. doesn't feel as consistent.
-I've seen people spawn into walls during deathmatch play and I've seen a glitch where the bomb isn't where it should be. (different on others screens)
-I personally haven't had issues with matchmaking, but I've seen a ton of issues with it from high ping and region issues to outright failure.
-tedious/minor other little things like the buy menu and the fact there's no close on buy option. plus characters all look the same with no variety like before
I'm sure there's a ton more but hey, at least the maps have a bit more detail and the smokes look nice. It should still be in beta imo
