How fast it will be? I wonder if I can really clear a dungeon and leave it before the corpses are starting to disappear and enemies are starting to respawn?

What? This question ONE YEAR before release?

hopefully they get this right. it will probably be tricky to balance with the public dungeons. but i think the enemys you kill should stay dead while you are still in the dungeon.

Hope they don't do that thing I've seen in a few games (most recently GW2) where you can kill a mob, and have it immediately respawn right beside you. Makes for horrible and stressful gameplay.
