You did somewhat poor DPS in our 10m ICC from what I saw. I know your gear isn't quite as good as many of our other raiders but make sure you're well versed on your DPS rotation:

I wasn't paying attention to your healing and disc is pretty hard to judge from meters so I'll say that I didn't see any real problems there.
