So i know we are still a ways off from muitiplayer, but first things first. Will MP be the same as games like diablo 3 and POE where outside of your current party towns are the only place to see other travelers or can we expect (hoping) more of an open world server like Diablo 4 Demo showed us where you can run into people anywhere and this leads into what i really wanted to suggest.
World Bosses! - Can we please have bosses that require at least a full party or even more if we can open world map. Perhaps these bosses can even tie in with the newly introduced time rifts and a party (or more) can enter the same time rift clear it and spawn the boss at the end. Tying this into item hunting would be that each time rift spawns its own unique boss based on the era its located and each rift has its own specific drops that cant be found elsewhere :))
