Whos to say they are low level.

With you thinking it would be ok for SE to delete their character completely just because they left they game, oh wait they used to do that in FF11.
i said "IF" there low level.

if they delete there characters they have everyright to do so its Square's IP not yours mine or anyone else. and you said ok to it when you made your account the terms of service say no explanation need for them to do what ever they want want. SE is atleast doing good business and asking the community what should happen to the game & allowing people to come back without having to make a new character.
