Probably the worst thing about World of Warcraft is that your account can be stolen by hackers. Like a Republican at a casino, you spend your whole life working hard and saving up material possessions only to lose everything in a single second of bad luck. There are two ways of eliminating the problem:

1. Become more spiritualistic. Instead of the game functioning exclusively on materialism, you could have a mode, or maybe one of the factions, where skills and abilities are independent of levels and items. This way, there is no difference between a lvl 1 character and a lvl 100. The difference comes from your abilities, not those of your characters.

2. I'm not sure if this one would work, but maybe you could create a small piece of hardware people could use instead of an account name and password? It could plug into a usb slot, and would automatically log into an account hard-coded to the device.

Both ideas have their merits. I still like the idea of making one faction communist and the other capitalist. That way, people can learn about the tactical, rather than what they consider moral, aspects of each system.
