The bug in the current version is due to a missing Combat row (row #3) on the GearList tab. One quick fix (without affecting the formulas) is to copy cells [G2:T4] on the Sorted tab and and paste special (values only) to cells [H2:U4] on the GearList tab.

You could also add [Don Rodrigo's Fabulous Necklace] which is a world drop.

I have no clue how to use the table function, so here's the numbers.

At the moment, Thundering Skyfire Diamond is sitting at 76.8 for Muta, and 96EP for Combat.

His numbers are actually pretty far off. TSD doesn't proc every 45 seconds - as I recall, its 1PPM with a 45 second ICD so usually procs slightly under once a minute. Its thus in the neighborhood of 48 haste rating (average case), and hence around 57 EP for Mut and around 70 for Combat - perhaps a bit more, as the nature of short-duration procs is that they tend to slightly overperform the average case in real fights.

You sure you're not looking at combat?

Those aren't the EP values for Combat either. To be honest, it sounds like you're looking at level 80 EP values, but I don't have a good feeling for where you're finding them - its not the spreadsheet linked in the first post.

Ok, I just need to make a quick request.. Can the items be updated to show ilvl or at lease the (H) tag in the first column of the spreadsheet? I just bought out one of the normal ones because I didn't notice that it was the (H) version listed as BiS.

First off, thanks for compiling this spreadsheet, it has been very convenient.

However, correct me if I am wrong, but wouldn't it be logical at this point to set the hit rate EP to equal the EP of the lowest stat, which is crit (I'm solely talking about assassination)? To elaborate, theoretically if one were at spell cap and acquired a piece of gear that put them over the hit cap, they would then restore a prior reforge. Since obviously crit is the the first on the list when it comes to reforging to reach the hit cap, the absolute minimum they would gain is additional crit in exchange for hit. Naturally, if they reforged a better stat like haste, they derive higher value for acquiring said piece of gear, but the absolute minimum would be 0.9. The only instance where acquiring additional hit would yield 0.75 EP is when one able to reach the cap in pre-raid gear without reforging, and although I could be wrong, I would think that this is quite unlikely.

At current gear levels mastery makes the most sense for the value for hit, as you're always going to reforge to stay at the spell hit cap - hence, the only thing that changes is how much mastery you can reforge vs how much of your available reforges go to hit. Eventually, you reach the point where setting it to the value of haste makes sense (because every piece that can be reforged to mastery already is, and to dump further hit you need to reforge to haste), but that doesn't generally happen until pretty close to BIS.

After the PvP Season 9 has started, I was wondering, if the Gladiator Weapons are worth using for Assassination in PvE. The Question is, what is the higher DPS on a PvP Weapon worth, compared to more Stats on the PvE weapons?

A "Test" with http://shadowcraft-test.appspot.com/ showed me a slight DPS increase of 4 DPS for [Vicious Gladiator's Shiv] against [Throat Slasher].
I wasn´t able to compare [Steelbender's Masterpiece] with [Vicious Gladiator's Shanker], because the Gladiator MH isn´t in the Database of Shadowcraft, yet.

I hope you can help me with that. Thank You.

At the expense of using the same Delicate Chimera's Eye somewhere else.

When comparing socketed with unsocketed items, always use the value of a non-JC gem as a basis for comparison, unless you have fewer than 3 sockets on your gear overall.
