WoW Freakz link: https://www.wow-freakz.com/spells.php?spell=226512&&name=sanguine-ichor
Bug description: Sanguine should be affected by damage reduction effects. Watch the official video. At 20:00 he tried to suicide on a pool with 9 stacks of sanguine (9x15 = 135% hp) but he survived one tick. Demon hunter has 20% passive damage reduction from all sources (Demonic Wards), he also had a proc from Aggramar's Conviction and 4 stacks of Painbringer.

Maximum health: 11955k
Damage taken: 10280k (approximately 86% max hp)

Sanguine damage * passive defense * painbringer * versatility = damage taken
Assuming he has around 20% versatility (10% damage reduction) :
135 * 0.80 * 0.88 * 0.9 = 85% (very close value)

Proof: Let me know if it is not enough proof

Could you add more info about this?. I dnk exactly how to work in retail, but in our core, the spells with Damage Percent Auras like Sanguine don't take account the reduction effects, this is general and also can happen with class spells like Decomposing Aura in Blood Dk

Watching videos in slow motion can help a lot

BURSTING AFFIX https://www.wow-freakz.com/spells.php?spell=240443&&name=burst
At 10:32 you can see his versatility damage reduction is 6.82%
At 10:48 his maximum health on demon form is 19314k
At 10:50 he takes 5240k damage from 1 tick of 8 stacks of bursting (40% HP each tick), he also has 3 stacks of Painbringer (9%)

19314 * 0.4 = 7725k damage from bursting

bursting tick * demonic wards * painbringer * versatility = damage taken
7725 * 0.8 * 0.91 * 0.9318 = 5240k

Few seconds later he used Empower Wards and take 3688k damage, still 8 stacks of bursting
See screenshot taken from 10:52

Spoiler:

Empower wards: 0.7
7725 * 0.8 * 0.91 * 0.9318 * 0.7 = 3688k

Then painbringer fades and the last tick of bursting damages him for 4031k
Without painbringer:
7725 * 0.8 * 0.9318 * 0.7 = 4031k

Spoiler:

QUAKING AFFIX (couldn't find spell link)
As far as I know quake should deal 20% of maximum health, not 10% like now

At 1:10 he has 8.95% damage reduction from versatility
1:42, his maximum health is 11834k
At 1:45 he takes 1788k damage from quake

11834 * 0.2 = 2366k quake damage
2366 * 0.8 * 0.9105 = 1723k (not so close)

At 2:06 he has Concordance active and takes 1507k, which is lower than before. I don't know how much versatility he had.

It seems the quake is not affected by armor.

Official video is the same from BURSTING.

VOLCANIC AFFIX https://www.wow-freakz.com/spells.php?spell=209862&&name=volcanic-plume
At 8:15 the mage has Devotion Aura and take damage from 2 volcanic plumes at the same time. Also there is no animation from Blazing Barrier. The paladin was near the casters, so devotion aura was affecting them for 5% damage reduction. The mage had 93.4% health before the hit, and 4.1% after the hit.

Damage from volcanic plumes
50 * 2 = 100% hp

Damage reduced by devotion aura
100 * 0.95 = 95% hp

95% is higher than 93.4%, so it is affected by versatility since mage survived with 4.1% health.

Spoiler:

EXPLOSIVE AFFIX (couldn't find spell link)
This time I don't have good proof but take a look.

At 12:32 an orb explodes and both tank and healer seem to lose less than 50% health. You can see the Empower Wards animation on tank before the explosion.

Official video:

Spoiler:

GRIEVOUS AFFIX https://www.wow-freakz.com/spells.php?spell=240559&&name=grievous-wound (don't know if it is the correct link)
Again I don't have good proof. I don't know if it is 3% damage per stack or 5%.

At 11:01 his maximum health is 12396k
At 11:43 he takes 1108k damage from 5 stacks of grievous
At 11:48 he has Demon Spikes and Concordance active and take 590k

I don't know if grievous wound should be affected by armor

Official video is the same from sanguine:

Spoiler:

CLASS SPELLS
I don't know if all class spells should work this way. According to this fix, Cold Blood always deals its maximum damage but Greater Pyroblast is affected by damage reductions.
Decomposing Aura doesn't do any damage, it just reduces maximum health as you can see in the comments.

I also noticed this we did EOA 15 back then with the bursting affix , the DH tank would always die he seems to take more damage than us even tho we have the same stacks and he have no other debuffs , i know it deals percentage HP we should kinda end up with the same percentage and with all tanks tankiness talents + versatilities actually he should take lower damage than us but that was not the case he ended up dying all the time every big pull on those crabs.

P.S it may have something to do with demon form? bonus HP then the bursting damage snapshot and he go back to normal form with reduced HP but take the damage of the percentage HP of that demon form?

I've fixed the dmg for Grievous, currently we are making tests for other spells with a fix for effects like explosive
