Topic: Enforce a 1 account only rule
I think players should only be able to own one account. There's loads of reasons why which are well known but I think the key point would be how to do it without bloody murder.
I suggest allowing people with more then one account to select which of their accounts they want to keep and then sell for real money the remaining accounts. Make using multiple accounts against the Eula with bans as appropriate for the people who try and use proxies etc.
Some benefits for the players:
Less steep gap in between new and old players (as how do you compete with a guy who has ten accounts when your new)
Greater end game content - less specialisation gives you a reason to want high ep accounts
More balanced PvP - your no longer competing against fully specialised players who mine with other accounts or against multiple boxers or vs ten scout alts
Cheaper for new players to come and join in - no 'two accounts are mandatory' mentality
Some benefits for the Devs:
More money from account ep resets not just for the accounts that move hands but for single account people who would reshuffle ep more often
You could charge one ice to change accounts
Easier to balance
More longevity of content
