I wouldn't mind an hour for people who drop out of parties as it's painful to wait for the system to replace that player. Yesterday someone left the group because they didn't want to "waste" their leveling on a lowend dungeon. Spent 10 mins waiting for a replacement... and it happened twice. So I wouldn't mind an hour punishment for leaving that. I dunno how I feel about the other ones, but going from 30 mins to an hour I'd support.
