I agree they should add PayPal, many MMOs now have it as method of payments. I payed stuff with PayPal (with bank account) like Diablo III: Reaper of Souls expansion (directly on Blizzard's website, Blizzard takes PayPal now), many free-to-play like Champions Online, Neverwinter and asian MMOs, even the recent Elder Scrolls Online has PayPal (payable with bank account), which I used. The old Ryzom MMO has had PayPal for close to a decade now. I don't have a credit card, cannot have one, but a debit card with credit card logo so it can be helpful, but I'd rather use PayPal instead. Beside I had issue paying at first with my card, SE refused my card but it passed the second attempt.
