I believe the alternate characters are necessary, but it is also understandable that the massive creation character can alter the performance of the servers I propose:
1. allow delete characters in the main menu of characters.
2. characters who have not bought with money objects have a period of 3 months of inactivity before being deleted. (who have been bought with money can not be deleted)
3. for the main characters but inactive, the option "vacation mode" would allow him between 5-6 months, which could be increased by just logging on and put back "vacation mode"
This would help the players and to the performance of the servers, I hope serve something thanks.
