Okay, quick and dirty maths before falling asleep!
Suggestive's data: Immolate hits - 712 - 713, Immolate crits - 1488 - 1489
1488/713 = 2.086956, 1489/712 = 2.091292
Oprahwinfury's data: 588-589 Non Crit, 1229-1230 Crit
1229/589 = 2.086587, 1230/588 = 2.091836
[top]> It makes your crits go from 200% to 209% crits, the bonus goes from 100% to 109%.
This makes crit 9% more useful than it is right now for damage, so if you had 1 crit rating
0.8 dmg before, you now have 1 crit rating = 0.8*1.09 = 0.872.
How does that work formula wise when a spell that hits for 100 damage crits?
Perhaps (100 + 50*critmod_talents+1.03)*1.03?
It would be 209.09, which is between our upper and lower borders from your numbers.
Isn't exactly the same how the hunter numbers work, sadly.
So, anyone with numbers how it affects spells that crit for 150%?
