So you could duplicate your existing character. As a result youd get a character of same level, same breed, same research and ai level but naked (it would be also nice if it had quests done and all nodrop items). That makes sense if you have a dedicated twink, you enjoy it but cant make your mind if you would like him to stay at current level or level it further or you have an endgame character but differences between pvm and pvp setups are so big you cant enjoy both of them. Leveling exactly same character aint fun at all and i think it could also boost FC revenue as it would be very tempting to try some other breed on those so breed change would sell more.
P. S. Please dont say that leveling is easy because you can get kited. If its so, im willing to pay you for 1-150 leveling, go and kite me.
