I want a 2nd Physical Attack...

Wow Web Stats from Mondays Bloodboil Fight(the try when we downed him):

http://wowwebstats.com/rqhfcywfdwixa?s=9932-10543 - DPS: 771
(I died at 5% left on this try and I was gimped for stamina)

Wow Web Stats from last nights Gorefiend fight - with a shaman in our group:

http://wowwebstats.com/c55rvmah5u6kw?s=5191-5509 - DPS: 1086

Quite a difference!

Now can anyone explain how i managed to miss so much when I'm hit-capped?
