Yes, but this doesn't explain the other hit in the same instance with no Instructors in sight -- just mobs with especially high crit ratings?

It's been stated that effects like Eye for an Eye still trigger on critical hits that are converted (and thus appear in the combat log) to normal hits.

From experience I would say that resilience and defense stack. I have been running a tanking setup the last few weeks with only 407 defense and 21 resilience. Over this time I have not been crit once in many Kara and Gruul's raids.

I believe he was aware of that, but was pointing out the fact that eye for an eye procced off of a spell crit, that got converted into a spell hit via resilience. That's all fine and dandy except for the tiny detail that it was a mob vs. player spell crit ... which to my knowledge isn't supposed to happen. Ever.

Wearing resilience makes it so your abilities like enrage, blessed resilience and the like go off even from mob spells which never actually crit. I think you can even stand on a bonfire and have them go off occasionally

So, the way this works ... any crit based ability will trigger from any hit roll of (100-resilience based crit reduction) to 100? As in if you have -2 chance to be crit any hit roll of 99 or 100 will trigger those abilities even if it wasn't going to be a crit to begin with?

The Cabal Fanatics, from the 2nd screen shot, are the ones that turn into a mini-core hound at low health if I'm not mistaken. Wasn't there a patch note about a buff to this ability a few weeks back?

My bad here, its the zealots that turn into core-hounds, disregard please..

This would lead me to believe that instead of making resilience prevented crits still proc things, they faked it by adding another effect to resilience, where it converts normal hits into "special" hits. As long as an ability's crit rate isn't negative, this works fine, but once it is you start getting more crit procs than you would without the resilience. What would be interesting to test is what happens when your resilience crit reduction is higher than your incoming normal hit rate, although I doubt that's actually doable.

This is correct. A crit that is converted to a non-crit due to -crit (not quite sure if its just resilience or also includes -crit talents) will still proc an ability that requires a crit.

Proves that you can get 'resilience critted' by damage that should not be able to crit you.

::Edit:: I was wearing 20 resilience rating.

I think we should stop making the assumption that all mobs have 5% based crit; it's probably true that mobs have 5% based crit due to weapon skill, but in his first screen shot, we can see that the instructor actually missed him. which means his def skill is higher than the mob's weapon skill and not the other way around. there are mobs that have crit players for some random amount before, but blizz probably made mobs that could do 25% of the tank's hp in 1 swing to have only the minimum crit. be cause if u think about it, if a mob can do 25% of the tank's hp in a swing, and being able to crit double along with crushing blow, there is no way to do the encounter without some amazing gear. whereas mobs that aren't as difficult, but could be a bit difficult to make the instance a bit more interesting, could be tuned to have a higher crit chance than, let's say, the bosses.

what intrigues me in the first screen shot is probably the damage difference there. but maybe the hits were from the instructor's offhand, and the crit is from the mainhand.

unfortunately we really don't have any concrete evidence of mobs doing higher crit chance than the said 5% (+ lvl difference), and blizz probably won't release that sort of info to us. if one really wants, he could probably get a tank and 4 healers, and have the tank take hits from 1 of those mobs for like 3minutes straight and parse the combat log for hits and crits. then we'll have a rather accurate estimate.

edit: the resilience thing is interesting; I wonder if they really just slotted the resilience system into the calculation. they probably did, since it'll take some major over-haul in the combat calculation if one was to add in a variable "correctly"

If I had to guess it would be that certain mobs have higher-than-default combat skill thus rendering your usual defense cap too low.

Well, seeing how Spell Reflect (warrior) doesn't generate any threat for a warrior tank, I can't imagine a 5% chance for 30% of thier damage (and it being extremely hard to test), I'd still venture those points aren't the most useful.

Something more interesting occurs to me, though.

If Resilience occupies a spot on the to-hit table...

And doesn't only displace existing "crit" (as evidenced by the E4aE shot, where a NPC spell that has no crit on it's hit table still rolls resilience and then triggers a crit reactive)

does that mean Resilience rolls will displace other effects in terms of to-hit?

IE... on a crit-immune player, who also has Resilience, will that "resilience hit" chance also push some crushing blows off the table? Like other defensive effects do?

The idea seems interesting to me. To be sure, it's mostly just an intellectual exercise since you can only get like 2-5% "resilience" realistically without throwing out other defensive stats. But who knows, there may be a way to exploit the idea if it is so.

I couldn't imagine how to test it without standing someone in front of Anachonos for six hours, though.

I would theorize that instead of actually making enrage-like proc on "resillience prevented attacks" they made enrige-like procs able to proc off normal hits with a percent depending on your resillience.

On the getting-critted-with-500-defense issue, it seems more likely to me that they increased the mobs weapon skill than its crit rating. Not that it matters much i guess.

But you can't be sure of that, though. Neither explanation has evidence against it, yet.
