Diablo 4 is extremely disappointing so far if you care at all about the game glitching out randomly or playing with a friend on the same screen. Anytime you attempt to play 2 player Co op on the same screen either player one or player two will have terrible glitching on every button command. It is so bad it makes the game unplayable. Hopefully they patch this so others don't have to experience this same disappointment. It is worth noting that I am not playing the beta, these problems are with the finished game
