A different questing system would be awesome =D

Having a 'Leve case' to see all of the Leves you have completed (Sorted into Areas/etc)
As in Leves could range from a whole variety of different types =D And were like achievements in a way (E.g 'hey look I did this [link leve]').

having certain leves that allow you to do certain things, which could then allow people to trade certain leves.

Could put a limit on leves done in 1 day? (not 24hrs, but just as soon as the timer ticks for the timezone).

-- Having something separate for normal questing.
