so, i might unsubscribe for a month or so and was wondering, since i want 7 characters in one server and the limit for preferred is 6: If I buy the extra character slot now as a subscriber (making my slots 13) then go F2P, would I still have that extra slot when i'm back down to preferred (7th character slot)? Or do I have to purchase when I WANT to unlock it (when I unsubscribe)
