Mitigation question

[Kalise]

This is a very bad illustration of mitigation. Healing and Regens are not mitigation because it can not help you survive an attack, Healing can only help you recover from attacks.

Which you'll note I mentioned in my post.

For attacks that deal more than maximum health of damage, healing does not help to mitigate it.

However, for damage that is lower than maximum health (I.e. Literally every single attack in the game, provided you use a relevant CD), healing will then mitigate the effect of it.

It has been a long time since 2.0 when there existed a particular boss and a specific Tank kit wherein one-shots where an issue to the point of nullifying healing as a form of mitigation. With Tanks now having a plethora of CD's that bolster their EHP so as to prevent one-shots.

As such, there is more value in self-healing, if you can self heal more than what an additional CD would provide (This is basically only notable for WAR as they are the only Tank with a choice between damage reduction (Raw Intuition) or healing (Nascent Flash)). This becomes compounded when you factor in potential CD stacking and its effect on the Diminishing Returns of damage reduction effects:

I.e. Rampart + Raw Intuition isn't 40% damage reduction, it's 36%

Thus, if there was a case where a Warrior with 100,000 HP is facing a 110,000 damage attack then;

With just Rampart for 20% DR he'd take 88,000 damage and be left with 12,000 HP

With Rampart and Raw Intuition for 36% DR he'd take 70,400 damage and be left with 29,600 HP

Meaning that this RI usage is only worth 17,600 HP and thus, if he could heal more than that with NF (Which is easily done, simply NF + Infuriate + IC is at least 60,000 healing) then the healing is superior mitigation given that he'll be surviving the attack even without RI/NF and simply Rampart.
