Mapping in a group feels bad.

Playing maps in a group is no fun at all. Sometimes you just die. Especially at the beginning when you've just reached the endgame. Or from chaos damage, because you don't have any resistance to it yet. My colleague opens a nice map and we walk into it. I die at the beginning. What do I do now? I can't get back into the map. He can't revive me. But I can't do anything of my own in that time either. If I open a map myself in that time, I won't finish it before my colleague. And if I don't finish it, it closes again after a certain amount of time. So I can only wait 10 minutes in the hideout and then I lose interest. That's kind of annoying. Of course I could just open a map and my colleague comes into my map after his map. But isn't there perhaps a more elegant solution that doesn't affect the feel of the game as much? Perhaps a consumable item with which you can revive a player once in a map (without bosses). But at the moment it's a bit unpleasant.
