This is a idea what I noticed is the game becomes repetitive after like the 3rd character it gets boring to level a character because same exact questline. I was thinking same concept as WoW you level till a specific level at one spot and choose where you would like to continue next, for example lets say your level 10 you can hop to Mooshu if you like questing in Mooshu and those specific bosses and mobs are automatically adjusted to your level just for you though. Same exact concept as World of Warcraft, it makes the game more fun and non repetitive really.
