Balance analysis of 2.1 WAR proposed changes

[Vire]

Effective HP is a function of total HP and guaranteed bonuses. It does not concern healing bonuses at all. WAR and PLD have nearly identical base HP, and WAR gets +25% HP while PLD gets a 20% damage reduction which is an effective increase of 25%. WAR is slightly ahead due to the 85 HP advantage the job gets at base.

The problem is you are not taking into account that filling up that 25% extra hp on both tanks are not equal.
This is why you do effective health because this is not very clear unless you show how much actual hp a Pld and War have when it comes to healing and taking damage not just the total number when they are full.

edit:

This fine poster did the math already so instead of redoing it ill paste it.

Effective health:
Assuming both have 5500 HP before stances
Warrior: 5500 * 1.25 = 6875
Paladin: 5500 + 20% dmg reduction = HP/(1 – 0.2) -> HP = 5500/0.8 = 6875
So without heals the effective health is the same, but things change once healing is taken into account. Tanks take 5k dmg over time and need to healed.
Paladin: 5000 * 0.8 = 4000 dmg to be healed
Warrior: 5000 dmg to be healed
Even with the warrior buff it is still a bit harder to heal the warrior. Paladin requires 4k to be topped off, if the warrior got 4k heals, with its bonus it would get healed for 4800 hps , 200hp short to be back up max. For the warrior to be healed to full with the same heals the paladin requires it would need a 25% healing buff instead of 20.
