The value of Armor Penetration goes up with the amount of Armor Penetration you already have, including that from trinket procs.

Since you have neither Mjolnir's Runestone nor Grim Toll, agility is probably better for you.

They're pretty close up to huge values of armor penetration, anyway. I offspec mutilate, as you do, and so generally gem for agility as it is far better for Mutilate on bosses that are Murder-able and most of my gear does double-duty.

Also, the poison cap is 237 with Misery/iFF and full Precision, not 315. Unless you tend to only raid 10-mans, you'll more likely than not have one or the other, so I wouldn't stress out about keeping your hit much above 237, though it's still useful for increased combat potency procs.

Could you please share your gear/gem/spem setup for these result?
Previously stated, combat pulled ahead by quite a margin. Have you found something others missed?

The reason I prefer combat is not only trash, but the ability to pop cooldowns at will, like when doing Deconstructor at hard mode to nuke the heart. Spreadsheet may be right about average dps and mutilate being ahead on murderable bosses, but I'd still find combat slightly more useful for timing cooldowns with bloodlust etc.

Just a quick comment here.

It's true that the Mutilate sheet hasn't been updated in a while, but then, nothing has really changed with the spec in that time; plus, the Mutilate modeling was always better than the modeling for the Combat sheet. Hence, assuming you've input all gear correctly, the answers you get should be largely correct, modulo one bug that's been reported.

That said: it's worth noting that the default assumption of the Mut sheet - that you get all set bonuses - is no longer particularly valid. So that needs to be kept in mind in terms of getting answers out of it.

That one bug, for the record, is that Rupture damage boosts are additive rather than multiplicative.

Regardless - I have no major plans to maintain the Mutilate sheet at this point - the modeling doesn't really need any changes, and the spec strikes me as inferior in most cases, so I'm just not willing to devote much time to it. However, given that the changes that need to be made to update it are largely straightforward, I suspect people's various third-party updates will be adequate for the moment.

On a vaguely related note: the new official version of the combat sheet has been uploaded. Please see notes in first post regarding behavior around the ArPen cap(s).

I'm sure plenty of people want to thank you for this -- I'll get it out of the way for everyone: Muchas gracias, Aldriana! = )

Now, onto more useful comments: I noticed this updated version lacked [Favor of the Dragon Queen], which is still a better necklace (for some rogues) than the [Broach of the Wailing Night] due to the gem socket. If you are not Aldriana and you have this necklace, you might consider inserting a line above the Broach and adding it manually to your spreadsheet. A simple search on these forums should reveal how that is done. If you are Aldriana, while this information probably has no benefit to you personally, if you have a list of minor updates, perhaps consider adding this piece of gear back to the sheet for others?

I made some effort to prune gear of little utility, partly for reasons of usability, and partly because the sheet does actually break in at least some versions of OpenOffice if the gear list gets too long. If I was overaggressive on some slots, I apologize, and feel free to request that some items be re-added; however, unless they're at least comparable to items in the sheet that are fairly universally accessible at this stage, I may decline to do so.

With regards to Favor of the Dragon Queen in particular: I actually thought I'd left it in - must've grabbed one more row than I meant to when deleting necks. When/if I get around to doing the next update, I'll probably add it back in - unless, of course, it's fully obsoleted by then (and given that I make no promises about the timing of the next release, that provision may or may not be relevant).

Maybe i am a little bit late for the discussion, but while playing with the sheet, the problem with the excellent 4/4 T8 bonus comes more aware(I think Aldirana stated, this when it was first discovered). I hardly find a combination of gear, where breaking 4/4 T8.25 before having 4/4 T9 (245) is better.
Thanks for the new version.

What would the rank be for Favor of the Dragon Queen when readding to the new spreadsheet ? I assume the base score is the same as the previous ... please correct me if i am wrong.

Ummmmm... I dunno how to answer that question. The base score isn't something you put in, it's something the spreadsheet calculates. If you insert a new row, make sure you copy the formulas from another necklace in the sheet, and just change the stats for it manually.

But for me, the Favor of the Dragon Queen is closer to the Seed of Budding Carnage than it is to the Broach of the Wailing Night. Your mileage may vary based on the gear you are using.

I've changed all item names to the Horde versions (and added Favor of the Dragon Queen) for myself and thought there might be someone out there interested in it. Although I like the idea of different models for Horde and Alliance, the different names are somewhat annoying, even if the only real variations are with weapons. It'll be interesting to see if they keep it up for IC.

Edit: I just realized that you have four active Glyphs, Aldriana - just in case you hadn't noticed already.
Edit2: And just now I saw your edit, Auturgist. Yay me doing redundant work.
