WOW is doing something really cool here!
If you haven't seen it already, Blizz is making a WOW Arena Tournament. Basically how it works is that you pay $20 and get 3 lvl 70s. They can be any race/class you wish and all the battles will be in the 3v3 arena.
Now they are billing it as a way for elite players to battle against each other but it sounds like it would be fun for even scrubs like us.

Check out the link above if you are interested. There is an FAQ but I'm not sure if say Gnomes can be on the same team as Tauren, but hopefully we can get enough people together here to form a couple teams and have a good time!
