We only have one computer between the 3 of us that can run the game(4 year old atom processors don't cut it lol) so it never really made sense to pay for multiple accounts if we could only play one at a time. I'm actaully in the process of putting something Higher end together for myself and giving my laptop to them, but they'll still have to share an account, and I'm not really sure if the Celeron laptop is up to the task of running the new update.
I know Hitech allows players to use he same account at the same time,just not in the same arenas at the same time.
