After getting dark knight 60 and playing it for a while

[Hundred]

DRK's have a great constant self heal, and have access to very short cd defensives. Other tanks work differently (paladin has many defensives, but all on signifncant cds. Wars have limited reduction compared to the other two, but more burst healing).

Inaccurate. Now I have to actually put out math for someone.


Lets assume attack speeds of 2.43 for instance. 7.29s for a Soul eater. 21.87 (max) for an IB.
0.8*1.15*260 = 239 which ends up as 32.7 Healing potency per second.
0.8*1.15*400 = 368 which ends up as 50.4 Healing potency per second (cannot be permanently sustained)
300 * 1.2 = 360 which ends up as 16.4 Healing per second.

Now your initial thoughts may be 16.4 < 32.7 <50.4. However this only perceives things in a vacuum.
Lets take a couple of considerations
1) Storms Path buffs the damage of Inner Beast if its up
2) Berserk further increases the damage output of IB.
3) Storms eye is an additional heal.
Now if we're using Storms eye as our other healing option to build up to IB for instance. Storms eye is
(0.75* 250 *1.2)/2 = 112 which can end up as 15.3 healing potency per second. With just Storms path and Inner Beast a Warrior operates around 31 healing potency per second if he chooses, now this is off by a bit as using IB pushes the potency per second of Storms path down by a bit. One would think this it but Infuriate by nature of allowing more Inner Beasts increases the Warriors healing capabilities further. The cross class skill Second wind is 3.3 healing potency per second. Equilibrium is 20 on top. Given we're also dismissing Storms eye 10% damage reduction and Inner Beasts 20% on top which only serve to make these heals more effective given followups from the opposition are decreased.
As well as HP regen on the server tick scaling with maximum health which a Warrior naturally has a slight advantage over Drk in base.

The thought process might be "Well second Wind and Equilibrium are to make up for cooldowns" it doesn't matter one lick. The point of the self-healing is retroactive, after you are damaged you recover back a quantity, this is even more relevant as you outscale content where your healing output may outpace the damage output of an enemy. Dark falters here, Warrior and PLD do not. Now one may think of Sole Survivor.
Mercy stroke if successfully used on cooldown its 0.5% of your heal recovered every second as a warrior. As a Drk its 0.22%. Sole Survivor is 0.16%. When successfully executed a Warrior's Mercy stroke alone is more overall sustain then a Drk using Sole Survivor + Mercy stroke.

It's not a winning argument. Drk's strength isn't having a healing advantage over the other tanks. At best one could say Drk gives up less damage *while* healing (though this may not apply against WAR), but their actual ability to heal is lower and this is rather visible on say an Ifrit solo. For Drk to get the most out of their self-healing they require a warrior OT to be putting up Storms path and Storms eye for them, the WAR just brings himself.

Now if we want to get out of absolutes and go into practicalities neither DRK nor War spam self-heal combos all day given their other obligations (Delirium, Storms eye, Enmity) but three of WAR's heals are off the GCD and can be weaved during this entire process whenever needed.

If a warrior actually wants to, they can manage 50+ healing potency per second and sustain it if it was just a test of who heals more. Drk caps out at 50.4 healing potency per second with the exception of Sole survivor + Mercy stroke which again a warrior mathematically does better with just Mercy stroke alone. Due to MP requirements of DA a Drk can't actually sustain 50.4 healing potency per second.

The deal is going back to magical mitigation because thats what Drk current excels at. There's not much value in discussing self-healing between tanks, it's not where Drk excels and if the intention is to make them excel in that respect the absorption would have to be higher due to Grits interference.
