I think instancing has its place in a MMO, specifically the Raid side of it. Otherwise you have the problem of the biggest Guild on the server having a lockdown on the encounter until they have finished and moved on (hi pre PoP EQ).
I used to love a proper open world Dungeon crawl on a PvP server though, I miss those aspects![]()
I can see the logic of that yes, for raids I could understand the use of some form of instancing. For dungeons though I have always preferred the shared dungeons , like in Daoc for example. It was awesome to just be one group of many within the dungeons (not least because when your group wiped you could send a whisper to someone nearby and get their healer to come over and res your group
) , never been a big fan of these instanced, just for you, dungeons.
