2010 here we go again

I have a few, like six 80s, with gear ranges from heroics to ICC is the only instance I can run for upgrades. An level 30 Orc Shaman has been sitting quietly by for 3 months now. Watching how some of my other guild mates have been playing their Shamans. I have decided to quietly level my Shaman , then once Cataclysm goes live, switch over to a Goblin. Yes that is right I am going to level an Orc Shaman only to learn the class and then switch over to a Goblin and do it all over again.
