To clarify, I'd like the option for individual players in a dungeon group to come back after death so long as the other party members remain alive, probably once combat ends if that'd be a possibility.
As someone who plays MMORPGs a lot myself, I like building a world in this game that reflects the kind of MMOs I have experience with, and I've never encountered a game in which death in a dungeon means you're out for the count for the rest of the dungeon- and I'd also just like the option to design dungeons from start to finish where every encounter is risky but is also designed for a full party of players.
Of course, this is all just a personal preference, but I imagine there might be other people who feel the same way, and would like to be able to design a gameplay experience that most resembles what they themselves have experience with.
