Personally, I'd suggest you try emulating a server and see the content that way
If WoW only cost maybe $5/month I'd say it'd be worth it. Part of the addiction has to do with the cost; you feel like you have to milk every last minute out of that $15/month. I think they could lower the monthly fee to $10/month for more overall profit, since it would attract a lot more casual players that use very little server time (thus netting you a lot of money while costing you very little in additional hardware)
