7 months ago Im pretty sure demon armor 20% heal bonus stacks multiplicatively with all healing sources like sihpon life. That means 0.40 x 1.20 = 0.48 = 48%... (if it stacked additively it would be 0.40 + 0.20 = 60%...) You should be healing for 48% of damage done with both up.
EDIT glyph is also multi not additive, it just make your base 40% siphon x1.25 = 50% and NOT 40+25=65%, then you slap another 1.20 multiplier from demon armor...so final amount is [ dmg x (0.4x1.25x1.20) ]= 60% of dmg is healed with all 3 up
To sum up, if just siphon life is up its 40% if siphon life + demon armor is up its 48% if siphon life + glyph is up its 50% if siphon life + glyph + demon armor is up its 60%
so if you are healing for 63% instead of 60%, 50% instead 48%, its actually 5% more than intended but nothing unusual here with rounding errors
EDIT2 I just realized there is +30% effect of armor talent which makes your demon armor multiplier from 1.20 to 1.26 so that makes us the last scenario with all this shit up
if siphon life + glyph + talented demon armor is up, formula is 0.40 x 1.25 x 1.26 and thats 0.63 = exactly how is your observed 1024/1629 = 0.628 = 63% in you last test
same with your first test, its siphon life with talented demon armor, formula should be 0.40x1.26 = 0.504 = 50.4% your numbers 820/1629 = 0.503 = 50.3%
next you tested siphon life + glyph which i already explained it is 0.4x1.25 exactly 50% your numbers 885/1770 exactly 50% as well

What is Happening: So I have done some testing to above and the numbers look not correct:
All test has be done at dummy in Orgrimmar.
I do with my gear (no procs just basic) 1770 dmg per tick with Corruption (IMPORTANT NOTE: Im using Fel Armor) to the dummy, accord to the Siphon Life talent that should give me back instantly 40% of a heal from the damage done.
1770-40%=708 back as heal. To this part is all correct.
If I do change to Demon armor my spell power fall down this is why my Corruption tick now is 1629 but thanks to Demon armor my heal received is increase by 20%. The amount of heal I actually receive after just armor change is now 820.
So i tried to figure it out what is actual percent of it so I went:
1629-60%= 977 not quite right what I actualy get but maybe its wrong caculation so I did,
1629-40%=651 now +20% from Demon armor 651+20%=781 still not quite the amount I do receive and then I noticed that,
1629-50%=814 and that is the closest that I do receive?
How is it caculated then from where 50% come from?!
Now it is getting more intrested:
Combine the 2 things togather Siphon Life 40% + Glyph of Siphon Life 25% and Fel Armor ON:
1770 (Corru tick on Fel Armor)
1770-65%=1150 and the amount I actually receive is 885.. So again I noticed it is 50%?!?!
1770-50%=885 !
Now we change armor to Demon Armor again and we do the same 3 caculations:
1629 (Corru tick with Demon Armor)
1629-85% (40+25+20) = 1384
1629-65%= 1058 +20% from Demon armor 1269
And now the top...
1629-63% (WHAT?!?)= 1024 and this is the amount I do receive
If my caculation is correct on every single Corruption tick being with Glyph and Demon armor I lose 22% heal.
I felt like I do receve less heal from my spells recently and now I can clearly see why. Can you please have a look into that?
Thank you.
What Should happen:
Corruption should heal warlock more. Possible Demon Armor or Glyph (maybe both) issue.
