Go 5 accounts. I started with 3 and had to play catch up to 5.

Make 5 shaman! PVP Instance
Make a pally on one account to tank. You can macro 1 button and hold aggro with your pally in 5man instances. Less management is good.
Make 4 other toons you like that can be grouped up with your pally.

Have fun and waste lots of real life time!

I have wow guilt for the time I spend playing.
