It's got some server issues for sure, but also just tons of crashing and bugs that require full restarts. Like, the mod for my main weapon is bugged and will sometimes just stop working completely. It won't start working again until I exit to the main menu and reload. I usually have to log in twice because I don't have a HUD after the first try, so gotta log out and log back in if I want to see my health, minimap, cooldowns, etc. Sometimes my friend's character will stop attacking or using abilities until he is knocked down or killed, rendering him useless. It's pretty crazy.
But with all that said, it's still pretty fun. Just hoping they fix those issues soon. If you ever pick it up and want to play it with someone, just hit me up.
