It’s no secret, farming MIs and other zone/monster specific items for your build means going back to the main menu and entering Cairne again immediately… over and over. This process on multiplayer, however, is far too tedious to be worth the time (connecting in multiplayer has been a hassle very often and disconnecting is incredibly bothersome).
Especially when taking friends around who are new to the game, it would be awesome to be able to farm a specific MI alongside them that complements their build, rather than telling them to go farm it solo to keep their build alive.
It would be amazing if an option could be available, or an NPC in towns created, that could reset the instance, respawn monsters, totems, and interacts, with only a loading screen or two between you and the reset, like in singleplayer, without anyone disconnecting.
