So, obviously the stat priority for Prot is a mess, and a big part of that is my fault. I confidently posted my AMR sim results, and essentially stated them as fact. At this point, I'm sure a lot of you are frustrated with the fact that Prot has no "official" stat priority and that it seems to change every other day. That frustration is completely understandable, but all I ask is that you remain patient while this is sorted out. In truth, no one really knows what the "correct" stat priority is. The reason for that being AMR and SimulationCraft both currently have their own issues and because of that, produce different results. We currently have two sources of data to go on, my AMR sims, the the SimC sims posted by celinamuna. As I just said though, neither are entirely correct/accurate.
To expand on this, here's a sort of list on the current state of things:
1) SimC is incomplete/bugged for Prot. Some artifact traits aren't implemented (I don't have an exact list, but I believe SoE and DS are both non-functional), a fix to IP was made after those sims were done, and there are a few more things I can't remember right now. I don't think it's fair/accurate to base a stat priority off sims that are only mostly working. Now, will implementing these things/fixing bugs make a huge difference in terms of what it shows for stats? Probably not. But I'd rather not base a stat priority off of a "maybe".
2) It's been suggested to go Haste > Vers > Mastery for "smoothness", and Vers > Mastery > Haste for reducing total damage taken. While that's most likely true, giving people two stat priorities to pick from isn't very helpful, especially when most don't know what TMI/smoothing/DTPS actually is and what they affect in terms of survivability.
3) AMR sims are not as bad as people are claiming. I definitely don't think they're perfect, and there's some work to be done in terms of NPS. Also, I agree that the stat weights generated by AMR are questionable at best. Strength is weighted too highly over Mastery, and Haste is weighted too lowly compared to Vers/Mastery. The "advantage" that AMR has over SimC currently, and the reason I used it to generate my results, is because from what I can tell, AMR does everything correctly in terms of buffs, procs, rotation, etc. The major flaw it has is its NPS metric.
4) There needs to be more work done in regards to SimC. For one, Haste breakpoints need to be figured out/confirmed. I did some initial testing, and Haste seems to fall off after ~28%, however I'd like to confirm that with SimC. Obviously I'd prefer not to do that now because of reason #1.
4.1) I don't think it's a good idea to base the stat Priority off one set of sims (I'm referring to the SimC sims posted above). The "problem" (it's not really a problem) with SimC is the fact that the weights that are generated only show you what will give you the most immediate improvement to whatever metric you're looking at. That doesn't help you create a general gearing strategy. Several "sets" of sims need to be run (in addition to things like scale plots) at different stat percentages in order to create an accurate priority (this is esentially what AMR attempts to do). One of the reasons for that is because of things like Haste breakpoints (see #4).
5) Haste is (very likely) the best stat for smoothing (TMI), however, in my opinion I don't think Prot will gain the most overall "survivability" from more smoothing. I think we are already extremely smooth (again, in terms of TMI), and because of that I strongly believe Versatility is far and away our best stat. I also don't believe there is a "right" answer to the smoothing vs. damage reduction argument. This is where the whole "philosophy on tanking" discussion comes into play.
6) Using all of the evidence/data we have (which is not completely useless by the way, it's just not necessarily "correct"), Versatility is still looking to be our strongest stat for reducing total damage taken, and as I have argued, thus for survivability overall. Assuming that this is the case, the question remains whether Haste is better than Mastery or vice-versa. There's an argument to be made for both, but considering Haste's contribution to DPS, and the effect it has on smoothing, it's definitely within the realm of possibility that overall, Haste > Mastery. However, this can't be confirmed in an accurate and reliable way until point #1 is taken care of.
So, perhaps our stat priority is Vers > Haste (to 28%) > Mastery > Haste > Crit. Maybe Haste is always second. Maybe Mastery is better than Haste. I can get a pretty good idea of what is actually better right now overall (leaning towards Haste for the smoothing/DPS reason), but I don't want to make anything "official" for all the reasons I listed above.
Finally, I'm somewhat new to my "position" (prot 'theorycrafter', prot guy, whatever you want to call me), and in hindsight I definitely should have handled some things differently in terms of how/when I presented information. The stat priority has (obviously) been a mess, which is something I'm trying to get cleared up/fixed as soon as possible.
