The server stability is horrid, to be blunt. My friends and I cannot connect for more than 5 minutes at a time without reconnection messages or just completely being thrown back to main menu.
This happens every time guaranteed when facing a boss or running crucible.
I know you want persistent servers but Moon, this isn’t it.
Let us host our own peer-to-peer servers, or have the option to create a permanent one on your side. Both options are going to be necessary if you want this co-op update to work and not turn people off from the game.
