I'm your quiet and friendly windwalker monk that likes to try and dps, and I'm always looking for ways to improve myself. I found this site which can analyze warcraft logs and see how you're doing individually. It's in BETA at the moment and not all classes are supported at this time.
Looks like this site is for a few healers and a few tanks too. Just plug in a warcraft log from one of our recent raids and queue up a report for any given fight. Example warcraft log:
I noticed that I'm energy capped for too many seconds and I'm about 85% efficient on using my abilities. So I'm going to try a different talent next week and see how it goes. Hope this can help someone too.
