AC Barely Reduces Damage
« on: February 12, 2019, 09:17:40 pm »
Against Emperor Crush we had Demodread the SK as main tank and Second the Berserker swinging and not really trying to pull aggro. Second took a bunch of hits partly due to fear and knockback and this gave me the opportunity to compare damage mitigation for both characters. Here are the results and some of the relevant numbers (I can try to give more information upon request)

Demodread
AC: 1795
Shield AC: 79
Shielding: 11
Average Hit: 255
Minimum Hit: 224
Maximum Hit: 325
Percent of Hits at Minimum: 34.1

Second
AC: 1277
Shield AC: 0
Shielding: 5
Average Hit: 272
Minimum Hit: 238
Maximum Hit: 339
Percent of Hits at Minimum: 29.4

While Demodread did take less damage overall, his advantage in damage mitigation was quite small. Part of the reason for this might be due to more than two thirds of Crush's hit damage being base damage and thus not subject to reduction by AC whatsoever (unless AEQ combat deviates from stock EQEmu in this regard). However I would also expect a much greater reduction in the amount that AC reduces the variable part of the damage (here the reduction due to AC seems to be an average of about 5 percent of the variable damage). It is possible that increasing mob attack and increasing the variable component of damage will result in AC being more effective overall.

So ... 518 more Armor Class ... a Shield ... higher shielding ... more Defense/Reposte/Parry/Dodge hopefully ... and the Defensive Discipline the whole fight ... yields and average hit for 17 less damage ... doesn't seem right /sad face ...

It's nice to see some numbers that corresponds to what i am seeing ... especially since when I see a wizard takes agro from monster nukes and they are nearly taking the hits as well as a tank.

Hopefully something that can be looked at ... placed a lot of effort to focus on tank gear, AA's, etc and that's not looking equitable.

Do you mean hits from Crush that were a result of his successful ripostes? Those hits are included in the numbers I have shared. Do you want them to be extracted from the file and analyzed in isolation? This is possible but would require a custom program to parse the logs since the program I am using doesn't differentiate. There were a total of 13 Ripostes against Second and 20 against Demodread.

another factor is total hits, im going to guess here and say crush attempted more hits on Demo than second here But id like to see a break down of the data. things like that will influence Average damage

Yeah, need a count of misses (dodge/parry/block/riposte).  A parse from a 3rd party player (not the recipient of the attacks) might not pick them up by type, and simply record it as a miss.

Is AC meant to increase damage avoidance (miss/dodge/parry/riposte rate)? If not I don't see how the avoided swings factors into a discussion about the value of AC.

I also ran some simulations for various levels of AC and attack. My full results are available here:
https://docs.google.com/spreadsheets/d/1mF-l5U6i5nodaPhUGnKW-Hr6d1qxXq-_0n-qtsg3_iA/edit?usp=sharing

If you want to play with charts, create a copy of the document.

AC in the document refers to the actual AC subject to soft caps and all the rest, not the amount of AC displayed in the character window.

As we can see from the data, the marginal value of AC diminishes to nearly zero as AC increases beyond attack. This seems to support my hypothesis that increasing attack of higher difficulty bosses will increase the gap in damage mitigation between tanks who choose to maximize AC and other characters for whom AC is not a primary concern.
