Thanks for your feedback, appreciate it a lot.Okay sounds fine... on ursoc i pulled like 270 with around the same ilvl (and i would consider myself a fairly mediacore arms because of it being my secondary specc as we have to many tanks) , but i use 878 weapon with 1 ETW (i guess you loose a bit there towards my gear)
Well you "can" basically still use HMS during BC as it does free dmg (around 1k dps for the whole fight so basically nothing), but if you are a heavy buttonmasher (like myself) and you push your macro ones to many (in the whole fight) you already wasted this, if you now overcommit on every BC, i kinda guess you gonna waste a LOT of rage into HMS that do basically nothing (not 100k, but i guess you can loose 10-20k on it) . So i would try taking it out of the macro and see the result (I "gained" around 5k, cause i had quiet a few HMS failures), if you have logs, you can check how many noncrit HMs you have, thats basically the "missed" ones.
Yeah i am doing the same (pushed me ahead of our other arms with heavy ilvl Advantage in every execute Phase, he was FR+MS prioterizing) .
Maybe a more experienced Warr has some more ideas.
