I tried a heroic last night and wipled twice on trash. I never even got to the first boss.
My tank was taking big hits and my healer was struggling to keep up. I figured my tank and healer would be ready, but seems not yet.

In my signature you can see the team I am running with. I got rid of one of my DPS shammy for a Balance Druid. The druid is not very well geared yet, but with the moonkin aura and the Earth and Moon debuff, he adds a lot to the team I think.
Please look over my team and let me know what I could be doing differently. Is my team ready and if not what do I need to get to make them ready? Seems there is nothing more that is worth getting in "normal" instances and I cannot find a way to get more spell power on any of them with instance gear. Maybe I am missing something?
