Consider this, go outside to a bar and stay there for like 3 hours. Boom alot more money spent dan 12,99.
2 weeks ago I couldnt sleep anymore at 05:00 am, so I went online untill like 11:00 am had a blast. I can go online when I want, servers are always up to date. So I guess my money is spent well, and ill gladly pay for wow.
If you don't want to pay just make alot of gold and you can play for free,
