[Bug] Berserker Stance

[Vokire-cenarion-circle]

@Ekbert-sargeras

In our analysis of 5178 hits, we show that when fighting +3 lvl mobs in Berserker Stance the measured crit chance was ~3% lower than expected on each individual test and also when doing a weighted average of all the tests:

Overall crit chance (weighted average):

• Spell book: 15.61%
• Expected: 12.61% (-3% crit suppression)
• Measured: 9.75% ±0.82%

Additionally, all other attack table results match what what’s expected when fighting +3 level mobs (comparing to our extensive log collection totaling ~10k hits) which further validates these results.

@Aggrend-1483

Critical Strike chance is reduced by 1% per each additional level the target has over the player. (So if you have a 4% chance to crit an at-level target, you have a 1% chance to crit a +3-level target, in both clients.)

@Vokire-cenarion-circle

The way WoW calculates crit rate is over ALL attacks. Crit rate is not based on hits only. In other words, if you have a 5% crit rate, that 5% chance includes misses.

@Vokire-cenarion-circle

+toHit items subtract from your miss%.

So, ignoring all defensive actions (Block/Parry/Dodge/etc…) if I have 20% crit chance, 20% miss chance, and 60% hit chance and I equip an item that gives me +5% toHit and +5% crit, my stats become 25% crit, 15% miss chance, 60% hit chance.

New hit chance = (Original hit%) + (toHit modifiers) - (crit modifiers)
60% + 5% - 5% = 60%

New crit chance = (Original crit%) + (crit modifiers)
20% + 5% = 25%

New miss chance - (Original miss%) - (toHit modifiers)
20% - 5% = 15%

@Aggrend-1483

There is some code in 1.12 that explicitly adds a modifier that causes the first 1% of +hit gained from talents or gear to be ignored against monsters with more than 10 Defense Skill above the attacking player’s Weapon Skill.

This means that the so-called “hit cap” is in effect 9% rather than 8% for a player with 300 Weapon Skill fighting a level 63 monster with a Defense Skill of 315.

If I understand correctly, your rolls should be (against a L63 target as a L60 character without modifiers other than your spell book’s crit%):

91% Hit Chance
15.61-3=12.61% Crit Chance
14% Parry Chance
6.5% Dodge Chance
6.5% Block Chance - Aggrend did not specify this functionality in his posts. Mirayne noted a ~4.5% block
9% chance to miss

It seems like you’re correct that this may be a bug… I thought originally there was a roll to do miss, dodge, parry, hit first then do crit/glancing blows. I could be misunderstanding something, though.

Edit: for clarity, I thought (prior to this thread due to an incorrect memory) it was a two roll system. When I saidI might be misunderstand something, it wasn’t related to the immediately preceding statement. Sorry for any confusion!
