Level up new party members
When a new party member joins a party, either the party members have to go back and re-play a bunch of low-level quests, or different party members will be at radically different levels and have different chances of surviving future encounters. Some way to automatically match the level of the new party member to the level of the existing party would be great, allowing them to continue on right away. An interface for reading up on the quests the party has previously done, in order to get up to speed on the story. There might need to be a way to remove experience auto-gained this way if a player leaves a party, just to avoid abuse.
