The server connection is constantly dropping and kicks you back to the main menu. It drops while playing, it drops if your Switch goes into standby mode, it drops if you hit the Home button. You cannot play an "Online" character offline, so if you made a character with friends then it is unusable for solo adventures unless you create a private lobby online. Then the game drops server connection and you lose any progress you made.
I suppose if you do offline mode this game would rate much higher, but I bought it to play with friends. Definitely avoid at this price and with these awful servers.
