Had an idea last night and wanted to use your Spreadsheet to find out. Unfortunatly, you don't have "Executioner" as an option for weapon enchants.
So looking at your setup, and trying the best I could to understand it, I think I managed to simulate having an Executioner enchant.
This is where I'm wondering if I've made an assumption, or have a misconception about ArP, so do rip it apart if you find fault.
Using the same formula for Mongoose to figure out Uptime (both are 1.2 PPM), I calculated
Uptime*ArP rating/Amt per 1%
0.59638*120/12.316238841
Which works out to be
5.81% average extra armor pen.
(Weapon Speed 3.5, 0 haste, specced for Blood Frenzy)
I made the character completely nude, gave him
[Ironsoul], but reduced the stats to 0. (using the phoney stats table)
So it came out to just being a naked Mace specced Human Warrior with a no stats Ironsoul. (I tried with other weapons, and still noticed a dps increase with executioner over massacre)
I then added "
+IF(C19="None",X111*(120/AL61/100),0)" (This allows for easy comparison between Executioner and the other enchants already available) at the end of the formula in cell
C62 (Average ArP) where
X111 is the Uptime formula
AL61 is the ArP value per 1%
Conclusion:
Executioner is better than Massacre for an Arms Warrior. This could potentially benefit fury warriors, though I think this proof enough to get Executioner into the Spreadsheet so further testing can be done with the Fury Sheet.
Can someone double check that I haven't screwed up? (Beserker will always be better than executioner, barring only theoretical situations, but perhaps a return to PvP weapons? At least for Arms based on this.)
