What is the actual player attacking mob parry chance? I've seen conflicting reports

at 70 it was 9%
at 80 it could be 12%, 12.25% or 13.75% according to the different people I've asked

granted from behind parry is 0% but what about when you are in front?

Hi, I currently have 40% ArP from gear (no gems) and 10% from Battle Stance. When my trinkets proc (Grim Toll and Mjolnir Runestone) I am over the 100% cap. Is it better to gem for Strength or Armor Pen in this case? Landsoul's spreadsheet says Strength, but other Warriors in high end guilds have told me Armor Pen.

Thanks.

The amount of work, re-work, and analysis that went into that spreadsheet is unimaginable. Although a Warrior in a high-end guild may do great DPS while continuing to gem ArP past an effective level, you should trust the spreadsheet. There is really no other source that can compare to it in terms of breakdown and analysis.

Also try Rawr, we've been putting many many many man-hours into the program and now DPS calculations are far more accurate for this sort of thing.

No offense,but rawr is still far from perfect.There are many items that are missing or wrong(especially proc values) as well as things such as the armor pen cap value (rawr doesn't "read" the procs of MjR and GT as armor pen apparently).Rawr goes too linear without looking on the actual stats,when comparing gear,to the point of showing something as an upgrade to your gear when it has lets say 10 expertise on it and u already have 25,simply because it would be BiS if you wore nothing.
Nonetheless,it's a decent tool for fast calculations,but wouldn't really trust it's results so much.Note that this is my personal opinion and you don't have to take it as granted,In my opinion, check for yourself and judge.

@ Vehemens:
As for armor pen etc,what I found in my calculations is that passive armor pen over 60% without the stance bonus,will benefit you for about 20-50dps compared to the 51%+proc value added.This happens mainly due to armor penetration's way of scaling(the higher value,the greater % of damage increase) and not because of anything such as diminishing returns in attack power,as Jothay said in Arms thread.

If you have the gear for it,go full armor pen,if not,which is the most likely if you don't have hard mode loot,better stick with the soft cap (50.47%) and grim toll.

Well, sometimes simulation is better than spreadsheet :-).

I agree. Like I said, some warriors will still do great DPS regardless and in practice, Strength gems may seem just as effective. However, is the player who is seeing just as much if not more DPS via Strength gems operating in an environment where Sunders are falling off or Shattering Throws aren't combined with Heroism?

My point was that if you want a definitive answer to the question of Strength versus ArmPen gems, the spreadsheet models the most effective approach based on proven combat values.

At what point would one re-gem all arp using the spreadsheet? I'm not yet there, my arp SEP for my current gear is .9758 and regemming puts it at .9893. However, should I re-gem for arp when doing so would put my arp SEP at 1, or after it gets that high while still using strength gems?

With the change to blood thirst being on a 4 second CD your gonna be using it more often, and with it benefiting so much from strength you probably wont ever be in a situation where arp is at a higher SEP than strength. This has been said a few times in the fury dps discussion thread. Also you look like your already very close to the point where your arp will be at 100% with a grim toll proc and once you reach that point the SEP of arp drops significantly.

This is completely incorrect.

You should be gemming for ArP once you hit ~40% ArP from gear. Not sure what the tipping point is. Check the spreadsheet.

Pilkington is, however, correct about the fact that if you're wearing a trinket such as Grim Toll that the SEP of ArP drops if the proc brings you beyond 1232 ArP rating.

The spreadsheet can tell you the answer to this.

I imported your gear from the armory and it shows arp with a SEP of .9087, so if you regem Strength it will increase your DPS.
