I've been trying since Thursday to wrap my mind around Rawr (the ProtPaladin extension specifically), but I'm not sure I got it yet. For the record and to see whether I maybe forgot a step, I did the following
1) Imported my character from the armory
2) Set up buffs that seemed reasonable to me
3) Increased the amount bosses hit me for (experimented with ca. 80k), enabled parry haste
4) Started optimizing
Then I'll get results that seem to value Agility very high. For example, 16 agility to boots flat out beats 22 stam until I set threat rating to 0 or close to it, and the overall scale to 0.8. Now, I'm confused and don't know whether Rawr is telling me something wrong because I don't know how to use it, or whether agility really _is_ that good. Itemization point wise, 16 agi is more than 22 stam after all, but I'm not convinced that's a good metric

And yes, I'm aware that "halp! rawr sez agility gud, that true?!" isn't a very good description, but I'm also kinda lost in what information is useful and what not. Maybe that my (true) avoidance is at around 52% if I remember correctly, which doesn't seem too bad, but my health is just barely over 40k, even with all applicable raid buffs. That doesn't seem that much in comparison to some others that post here, and make me think it would make, if anything, stam more important?
So the real underlying question is: are there accepted best practices how to tweak rawr ratings for ProtPaladin to make most sense? Rules of thumb that say (I'm making this up from the top of my head, so these examples will probably not make much sense) "set your scale so survival and mitigation ratings are close to equal", "make rawr optimize with additional constraints so-and-so", etc? To me, the whole thing is just very much a black box yet, and I don't like black boxes

Not sure where to start with the thing.
