Somewhat hijacking the topic here but is it worth it? I've been playing D2 on xbox, which doesnt require a gamepass, but I notied that it's required when I wasnted to play Devil's Lair. I cant seem to find an option to solo it either so the pass seems required. But are people queueing for it?

Get the $10 plan. I had the same problem with Helldivers 2 when I canceled.

Yes you need gamepass for multiplayer. I use gamepass essential, which is the cheapest option.
