My roommate and I live together and both play on the same server. He's on the PS3 version and I'm on the PC version of the game. I was just wondering if I could pay for his subscription this month with my credit card (the same card I'm using to pay my subscription on my account.) I know that this is a bannable offense on some games, so I thought that I'd inquire before doing it. Better safe than sorry! Any help is much appreciated.
