Here's something you probably haven't taken into consideration: Those meager 10,000 bots will be able to offer the best gear at the lowest price possible. Wal-Mart style competitive pricing. So little Johnny can get his uber monkadin fully equipped for 5-10 dollars. You, the legit hard worker will have to sell that one legendary item you found this week for 95 cents or less. This can encourage legit players to switch to botting. If they're doing it and not getting banned, then why not?
