Short answer: If you can near 1400 ArPen via gear stats, gemming and trinket procs then huzzah. If not, gem strength.
Blood wants 1260, not 1400. Blood-Gorged covers the rest.
Uh..I don't think so. In that case you should take into account Sunder armor (15%) and Faerie Fire (5%) also. It's always ~1399 regardless (you can aim for 1310 if you eat a hearty rhino and a piercing armor elixi) because all those stacks multiplicatively.
I just want to make sure I am understanding this right. I have a blood dk, and my Arp is at 464, and I have my needle encrusted scorpion which procs for 678 for a total of 1142 Arp. So would I want to start stacking Arp over strength?
http://www.wowhead.com/profile=us.medivh.taintsmasherProbably still stick with Str gemming. But sim it. Basically the problem would be that you will lose out on a lot of str when re-gemming to Armpen that it just ends up as break-even and maybe even a dps loss.
From EJ,
Should I be gemming for Str or ArP? This is the most asked question in our world today, and the answer is unique for everyone, and will take a little work on your part! I'm going to walk through how I answered this question for myself, and also for a fellow DK. This was essentially the character I was presented with: character planner . arptest - chardev.org - This gear set is fairly typical of people wanting to switch to ArP, 2 plus pieces of T10, Shadow's Edge, a few upgrades but still with a few holes in the gear set.
The first step is to download Kahorie's Sim. If you aren't going to put enough time in to do your own sims, its basically a guessing game, you can look at these two scenarios and gauge which char you are closer to.
I ran the current gear through the sim to calculate current EP with the following results:
EP Strength | 2.87
EP ArmorPenetrationRating | 2.94Seems like we are good to go right? Mmm not quite. Now you have to also consider the fact that regemming from Str to Arp will cost you a lot of Str. Essentially how I look at this situation is that you wont notice any large increase in dps from making this switch, and do you want to move forward regemming gear that you should be replacing soon? My advice was to wait until he could fill his serious holes and try to pick up his and maybe the crated legs. Resimming with these upgrades gave results closer to this:
EP Strength | 2.89
EP ArmorPenetrationRating | 3.16I'd consider this character to be pretty close to the break even point, he could probably switch and not really notice a significant DPS loss or gain. If you're gear is better you're getting close to an optimal point to make the switch, if your gear is worse, you definitely aren't ready to switch.
To give you an idea, when I performed the sim for myself after getting my my results looked something like this
EP Strength | 2.84
EP ArmorPenetrationRating | 3.57So I made the switch over to gemming as much ArP as possible while maintaining the Hit and Expertise caps, and needless to say, I was pleased with the results: (taken from 10m Festergut)

You have no idea how Sunder and FF work. They remove armor from the front-end of the calculation. The only thing they affect for end users is the maximum armor cap that we can ignore. They have absolutely no bearing on how much ArP rating we actually need.
Blood-Gorged, however, is added to the backend. It's another effective 140 rating.
From
Ghostcrawler, via WoWWiki:
The cap for Armor Penetration then is: (armor + C)/3.
Calculating the ARP it's done in 2 parts:
First up - the debuffs. These reduce your target's initial armor. For example, if your target has 10k armor and it gets 20% sunder, its armor would be 8k. The debuffs stack additively, so Faerie_Fire will stack with sunder, totaling a 25% reduction on the target, taking it to 7.5k armor.
Second, comes the formula provided, you grab the armor after the debuff calculation and to that armor you apply the formula (armor + C)/3 .....
Finally, food buff, elixirs, etc. are additive ratings that are combined later into the formula multiplicatively, similar to buff-Haste versus personal-Haste. That's an important distinction because it lowers the actual percentage you are gaining.
