I've reworked the spreadsheet and fixed some issues. Hopefully this can get added into the OP with an updated title:
https://drive.google.com/file/d/0B7KIuYOLWnOzZndOUmp5NEZOclk/viewDeathwing's Spreadsheet unofficial update v0.5 patch notes:
-White DPS and Heroic Strike interaction remodelled to account for white MH swings transferring into yellow swings, weapon skill and hit will now accurately scale with HS spam
-Remodelled Slam which will now correctly consider Windfury procs in regards to DPS, DPR and RPS.
-All DPR calculations will now properly account for damage and rage gain from windfury procs
-The rage lost from losing an auto swing due to HS/Cleave was being affected by mob mitigation twice, this was corrected giving lower DPR values
-Substituted values for Heroic Strike Rank 8 rather than Rank 9 which is unavailable in this patch
-Added equations for hamstring and slam which take into account global cooldown caps and rage limitations
-Additional items were added including devilsaur set and mask of the unforgiven
-Finding the BiS combination mostly involves adding hit until you are no longer crit capped, so a crit cap cell has been added to the DPS sheet.
-Ironfoe and Thrash Blade procs modelled using an apparently blizzlike 10% proc chance (lacking information in this regard)
-Improved accuracy of execute dps when using the execute switch tickbox
-R7 and R12 gloves hamstring rage reduction is now accounted for
-Increased special cap to 8.6% however the value of hit below cap still seems to be too low.
