Please fix healers problem without touching other roles

[Valkyrie_Lenneth]

first, do you play and have complete understanding of tanks? if yes then you would know that tanks have 2 subroles: 'sustain tank' & 'offensive tank'. WAR & PLD are sustain, while DRK & GNB are offensive.
now to answer to the part I quoted: WAR doesn't have both. between PLD & WAR, WAR mitigation is lower (even lower than GNB too). both of them have heals, but WAR is stronger on the heal part, while PLD is stronger on the mitigation part. GNB & DRK on the otherhand, they're not sustain tank, hence they get more DPS oGCDs & output in place of the heals that they don't have.

Do I play tanks? Yes. I was a pld main until stormblood, and since I've played drk, though not primarily, but I did clear p4s with it while current.

And didn't the war god Xeno throw a fit because war wasn't top dps during one of the ultimates? It has the best or 2nd best invuln, depending on the fight.
