Wow, ok turns out that Enhancement Shaman are really hard to box well. There are about 10-12 abilities you need to use and the longest cooldown is 3 mins. I tried using the macro from here and I was getting pretty bad dps in good gear. I downloaded a program called Shock and Awe and it tells you which ability to cast next. Seriously I had to stare at this thing while frantically hitting my abilities. I managed 4.5k dps self buffed, which aint bad and I imagine it will go up to about 6k-7k in a raid.

The problem comes in that I was staring at the box that indicates which ability to use next AND NOTHING ELSE. I can't imagine a movement fight where I have to avoid fires and be aware of other mobs. I can see now why some classes are slow to respond in chat. Talk about ridiculous concentration. Compare this to my faceroll rets and now I'm pissed that I spent so much time and gold getting this Enhance set put together.

I'll give it a few more tries, but it looks like enhancement is way too hard to macro for boxing. I guess I could be happy with 2k dps in just melee.... ok not really =)
