Lots of game breaking issues. I suffer for someone elses internet connection, it seems at times he has an easier time playing, despite him having connection problems. Co op is a farce, people leaving all the time. Also, you would need a 'rng modifier'. At times, the rng just makes no sense and keeps giving you the worst scenario possible with 7, 8 merges and summons. Listen to your players, since you obviously dont play it yourself. Cheers!
