Terrible players will stay terrible. Good ones will learn new classes quickly (if they don't know the class already).
I fail to see the problem if someone wants to swap their ____ for ____ or even buy an account with in-game items/cash. Making someone mash through 10 levels of rats and snakes won't teach them anything. Plus the rich will just have their friends PL them or equip fungi tunics. Talk about the "spirit of the game", Seb Croaking Dirk & Fungi at level 1?
The logic that trading/selling will destroy the low and mid game is extremely speculative. People are making alts all the time and half of them are just as clueless as 1999.
On that note, I have a lvl 23 necro for sale
