What do you mean? That glitch where you can’t move / get the “trouble connecting to server”-icon seems to happen since around OP4. It started happening to me near the launch of OP5 and Arcade hasn’t worked properly since then.
It’s fun for me. If you have to hold on to your Gnasher 24/7 it’s certainly not enjoyable. Classes have a nice variety and are all “broken” in their own way, but every class has a hardcounter. Fun mode, when it works and you don’t get the potato-squad on your team.
Give COGear/ Raam a try. They got a dropshot in their “random weapon”-pool which has infinite ammo and skips reloading as long as you kill someone with it. Even better when someone trades you their Boomshot (but it works with every weapon, including Heavy weapons - the only one that doesn’t work are the GL-rockets).
