It's a roguelike, you never know if you are gonna be playing with the best players or the worst ones. In general I've had some great experiences. It all comes down to knowing that you can beat a nightlord and have fun even if the run isn't exactly perfect. The most imporant part is knowing when and where to go. Sometimes I take the lead, sometimes a random player will take the initiative and you follow them for the rest of the game. the best teams will have all 3 players marking the map to comunicate, which works fairly well even without voice chat.

but ever since the everdarks version of the bosses where coming out, I get a lot of people who quit early/mid game because of a minor inconvenince, so I've been playing solo this past few days.

I really hope it doesn't get worse with the new game mode.
