re: NEW CONVERSIONS FOR LVL 80

TAKEN FROM A FORUM ON ELITISTJERKS.COM


Combat Ratings at level 80

--------------------------------------------------------------------------------

Hello, I'm the author of RatingBuster and TankPoints, I've been able to derive most level 80 conversion rates and formulas in my beta testing, which should be useful for WotLK theorycrafting.

Avoidance stats now have diminishing returns
This includes:
1. Dodge from Dodge Rating, Defense, Agility.
2. Parry from Parry Rating, Defense.
3. Chance to be missed from Defense.
(Blue post)

The following is the result of hours of work gathering data from beta servers and then spending even more time running multiple regression analysis on the data.

1. DR for Dodge, Parry, Missed are calculated separately.
2. Base avoidances are not affected by DR, (Ex: Dodge from base Agility)
3. Death Knight's Parry from base Strength is affected by DR, base for parry is 5%.
4. Direct avoidance gains from talents and spells(ex: Evasion) are not affected by DR.
5. Indirect avoidance gains from talents and spells(ex: +Agility from Kings) are affected by DR
6. and values depend on class but does not change with level.

7. The DR formula:



is the diminished stat before converting to IEEE754.
is the stat before diminishing returns.
is the cap of the stat, and changes with class.
is is a value that changes with class.

If you're interested in all the work thats been done to arrive at these results, everything is well documented in the following posts in this thread:
DR effect of avoidance stat observed, research begins
Defense data from build 8970
Cross testing with Defense, Dodge Rating and Parry Rating
Parry from Parry Rating and Defense
The DR formula, and Parry calculations
Dodge calculations
Druid dodge cap calculation
Level does not affect the cap
GetAgiPerDodge() algorithm


--------------------------------------------------------------------------------

Lets do a quick example:

Level 60 warrior
Defense without any gear: 300
Dodge% without any gear: 7.0076994895935
Parry% without any gear: 5
Dodge rating: 0
Parry rating: 0
Agility without any gear: 83

Put on some gear which gives
+8 Defense
+24 Dodge Rating
+20 Parry Rating
+21 Agility

How much Dodge% and Parry% do I have now?


Solution:
For a level 60 Warrior
1 Defense = 0.04% Dodge + 0.04% Parry (the rest are not important for this problem)
12 Dodge Rating = 1% Dodge
15 Parry Rating = 1% Parry
1 Agility = 0.0427% Dodge








Add the base values and we have:
Dodge = 10.2487108
Parry = 6.668054461


Answer: (These are the values taken in game)
Dodge = 10.248710632324
Parry = 6.6680541038513

Level 80 Combat Ratings and Stats

Note that the following data are only verified correct for build 3.0.1.8970 (9/23/08), and may change during beta testing.

Build 8962 changes:
1. Mana regen from Spirit nerfed at level 71 to 80, at level 80 the amount of regen is nerfed to about 78% of the original value.
2. Players lower then level 34 will now convert resilience ratings at the same rate as level 34 players.

Rating Level 60 Level 70 Level 80
Expertise(-1% Dodge/Parry) 10 15.76923275 32.78998947
Defense Skill 1.5 2.365385056 4.918498039
Resilience 25 39.42308044 81.97497559
Dodge 12 18.92307854 39.34798813
Parry 15 23.65384674 49.18498611
Block 5 7.884614944 16.39499474
Hit 10 15.76923275 32.78998947
Spell Hit 8 12.61538506 26.23199272
Critical Strike 14 22.07692337 45.90598679
Spell Critical Strike 14 22.07692337 45.90598679
Haste 10 15.76923275 32.78998947
Spell Haste 10 15.76923275 32.78998947
Armor Penetration 4.69512177 7.40384579 15.39529991

NEW: Armor penetration rating, all items had the "ignore armor" stat converted to ArP rating with a conversion ratio of 7 ignore armor = 1 ArP rating.
At level 70, 7.4 ArP rating reduces enemy armor by up to 1%.


To derive the formula, I used haste data from level 70 to 100:
Level Rating
70 15.76923275
71 16.96694183
72 18.25562477
73 19.6421833
74 21.13405418
75 22.73923683
76 24.46633911
77 26.32461739
78 28.32403564
79 30.47531509
80 32.78998947
81 35.2804718
82 37.9601059
83 40.84327316
84 43.9454155
85 47.28318024
86 50.87445068
87 54.73849106
88 58.89601517
89 63.36930847
90 68.18236542
91 73.36097717
92 78.93292236
93 84.92807007
94 91.37856293
95 98.31898499
96 105.7865524
97 113.8212967
98 122.4663086
99 131.7679138
100 141.776001

With the help of curve fitting tools and decimals to fractions algorithm:
Percentage = Rating / RatingBase / H
70 - 80: H = (82/52)*(131/63)^((level-70)/10)

And for reference, the values for level 1 to 70:
60 - 70: H = 82/(262-3*level)
10 - 60: H = (level-8)/52
1 - 10: H = 2/52

(RatingBase is the conversion at level 60)
