- all percentage based heal buffs stack, because they are tactics.
- all percentage based heal debuffs don't stack, because they are abilities (Curse of Khaine (DoK) => 13 pt tactic in torture tree...50% incoming healdebuff on crit)
so that should be 1 * 1.4 * 0.75 = 1.05
player is heal debuffed with a 25% HD and buffed with + 15%, +15% and a + 25% heal buff:
so that should be 1 * 1.55 * 0.75 = 1,1625
player is heal debuffed with a 25% HD + 50% HD(Strongest apply) and buffed with + 15% and a + 25% heal buff:
so that should be 1 * 1.40 * 0.5 = 0,7
player is heal debuffed with a 25% HD + 50% HD(Strongest apply) and buffed with + 15%, +15% and a + 25% heal buff:
so that should be 1 * 1.55 * 0.5 = 0,775
So these easy examples illustrate that stacking percentage based heal buffs is really effective, because they stack additivly and stacking heal debuffs does nothing.
One Realm has more easy access to percentage based heal tactics that are easily appliable to a group, which is tipping the balance in favor of that realm in raw healing output.
Tactics that come to my mind that are problematic are:
- Focused Mending (KOTBS)
- Blessing of Chaos (Zealot)
- Blessing of Grungni (Runepriest)
- Exalted Defenses (Warrior Priest) to a lesser degree, because it is not incoming healing, but the other Realm has no mirror
- mirror the tactics to the other Realm
- make it so that only the strongest heal buff applies, like healing debuffs
- remove the not accessable tactics
Addendum: This interplay with heal debuffs and heal buffs results in some healer combinations as not being playable, because the 50% heal debuff is too strong, when no heal buffs are present.
If i made any mistakes with my arguments then pls point them out
(Edit: IT was pointed out that 2 KOTBS can't stack the tactic Focused Mending, because the auras don't stack. Has somebody tested this? I dont have the means to test it atm.
I was relying on info from twitch chat in this VOD: https://www.twitch.tv/videos/744403794?t=05h26m10s )
