Suggestion on the subscription payment system.

I know that there's a few threads that are suggesting various thing on this and what not but I think that this might be an interesting way for the subscription thing.

How about we get one character for free and pay for more characters per month?
On top of that we get one retainter per character for free but pay for more retainters per month also.

Essentially you would get one character and one retainter for free and be able to play on one server. But if you want to play on other servers, you would have to either delete the character you created or purchase a subscription for extra characters. Along with that, if you want to have more retainers you would pay a fee per month for the extra retainers.

Any thoughts to this?
