Sometimes it's a pain in the butt getting you character deactivated because you forgot to add Crysta or funds to your bank account on payday. I would consider a F2P option but most of the game content would be restricted except the LS chat and Say.
If SE made Vana'diel more player friendly but restrictive to progression unless you pay your sub, I would think that would be reasonable. Maybe if you son't pay your sub, you can't leave your Mog House,lol! Your under house arrest until taxes are paid in full! =P
If you cant, well so what! At least we can still log into PoL and send messages to our friends. I tried XD
