I kinda cancelled my account, but the way I did it means that I can probably recover my account no problem. See, if the card you're paying for it with expires or gets cancelled, they put the account in stasis instead of deleting it six months after cancelling the account. This way, if I ever decide to play again, my account is almost sure to still be there. ^^;
Even then it's possible to recover a lot of accounts these days. With the playerbase mostly being stable, they aren't needing to delete characters to make room for new accounts. *winks*
The scary part isn't that I'm so high level... I'm pretty mediocre in my LS... we have dozens of people with 2 or more jobs at 75. >.> We're a crazy bunch. XD
