I agree Click and Buy is a terrible idea. After I found out FFXIV was going f2p indefinitely, I wanted to remove my credit card information from their site just because I am paranoid and don't want people to have my info if they don't need it. It was impossible and the only thing I could do was completely cancel my account. Something tells me though that they're still holding onto my credit card.

I have played many MMOs and have never seen such a convoluted registration and payment system. Why can't I just enter my credit card information in SE accounts page and then select an option for 1,3,6 months like pretty much every other company. That should be all there is to it, and it should be a process that takes 15 seconds.
