Checked that myself and 25agi = 1% crit is correct, yes.

I always thought ratings would be based on the levels of the targets... for example, running lower level instances like Stratholme for LBS, I would notice a crazy crit rate... it was half of what made bear-soloing (pre-nerf) a good portion of old content viable, since an iLOTP proc was guaranteed every ~6 seconds with swipe spam.

Anyone have any solid info on this? Or if crit/hit ratings even work the same way various higher/lower level mobs.

I'm getting 80int = 1% spellcrit for paladins.

Removed 44 int, lost 0.55% spellcrit.

 

woo-haa

The rating conversions is based on your level. The reason you crit more against lower level mobs is because of your weapon skill is higher than their defense skill.

That's part of the picture, sure, but I don't think it's the whole picture. Just look at the tooltip for Hit Rating on your paperdoll: "Increase your melee chance to hit against a target of level 70...". From that wording I would assume ratings scale back up with each level you have over your target; so for example 180 hit rating, which is 11.41% at 70 against a level 70, would be 18% against a level 60 target. Same with crit rating. For some ratings, however, I'm not sure how it would make sense (Defense, for example).

Another reason I think it works this way is because I know for a fact the inverse is true. Before 2.0 hit in classic WoW, I had 20% to hit with gear, 25% with talents. All of a sudden I was seeing misses against raid bosses, and the only explanation for that was the fact that I now needed ~11.2 hit rating per % of hit, or ~219.5 hit rating, rather than 200.

25 Agility is exactly 1% crit and 1% dodge for a Paladin at level 70.

Loud and clear. Thanks.

Bump, is all the first page information correct/updated? Thanks

I confirm this. Here are some data points for Paladin spell crit per int. The left side is total int, the right side is spell crit as indicated by the tooltip, mousing over Intellect in my character sheet:

382 = 8.11%
352 = 7.74%
328 = 7.44%
308 = 7.19%
296 = 7.04%
284 = 6.89%
262 = 6.61%
245 = 6.40%
229 = 6.20%
207 = 5.92%
178 = 5.56%
163 = 5.37%
147 = 5.17%
125 = 4.90%
95 = 4.52%

You can see in several places that 16 int corresponds to 0.20% crit. Also, 24 int corresponds to 0.30% crit. 12 int corresponds to 0.15% crit. These values all nicely point to 80 int = 1% spell crit. Then you could trivially solve and find that Paladins have approximately 3.33% base spell crit.

However, if you do the math, you find that with 80 int per spell crit and 3.33% base, some of the top-end results don't quite line up. So it might be a slightly smaller base with a very slightly smaller conversion rate.

(edit) I would do a linear regression here, but I don't actually have access to the tools for that, so yeah. Anyone feel like doing it for me? ;-)

Math on what 1 Def does for dodge,parry,block would be nice if anyone would care to take a shot at it.

 

Louviel

1 Defense skill gives .04% to parry/block/dodge and -.04% to be crit/hit by a mob.
AFAIK this does not change between classes.
Thus, since a druid cannot block or parry, he gets less benefit from defense.

1% spell crit = 80 int with a base of 2.355%

Wanted to comment on the formulas for mages, because the ones, available at this thread's OP are somewhat crude.

Crit ratings for lvl70 are calculated with this formula: CritRate/1148*52, which is about equal to 22,076923 rating per crit%.
Formula taken from here: http://wowwiki.com/Combat_Ratings

The best explanation of how int works is found in this reply, earlier in this thread:

Proof?

I am a 402 int mage with 249 crit rating, currently sitting at 17,21% crit for untalented spells (non-fire basically).

If we assume 22,1 crit rate for 1% crit and 78,5 int for 1% crit, the numbers add up only if you introduce a 0,82% base crit value.

However, if we assume that CritRate / 1148 * 52 + 5 + (Int - 327) / 80 formula, than the numbers add up nicely, with the formula giving us a 17,21625 crit rating (well within 17,21% crit, shown in Armory).

I won't provide my armory link, since it will expire as soon as i get an item upgrade , but if you still want it feel free to look up Maxi on Defias Brotehrhood EU. Or check the numbers against your own mage stats.

Rundown: 1148 / 52 Crit rating for every 1% crit, as well as 80 Int for 1% crit, with (5 + (Int - 327) / 80 ) formula for int.

Yes, i am nitpicking, but stuff like that is important if you want to make a perfect mage dps spreadsheet :P

Doing a linear regression of those points I'm getting a 79.85 co-efficient for int to crit. Looking at base of 3.3309%. I know it's shocking, results are extremely significant and the fit couldn't be better (99.999% adjusted R^2).

If you can get a copy of excel or something like that it's got the tools for at least basic regression modeling. (Tools -> Addins and check analysis toolpak and then there's a regression option under Tools -> Data Analysis).
