Personally I'm very sceptical when it comes to the competitive aspect of the multi-player version. In Larian's co-op highlight videos they frequently emphasise how you can straight up kill your party members.
While I can understand this evidently is going to lead to some banter between the players in 'real' situations I fail to see the purpose of killing your fellow players for the sake of a quest. Ultimately you'll have to revive them again anyway or they'll stay dead for the rest of the game, resulting in them essentially being indirectly kicked from the group. I imagine the self-resurrection partially was intended to prevent this from happening, but at the same time I perfectly understand why they decided to leave it out of the game.
