Storm's Eye and Darkside are both +20%. The more useful note would be trying to account for Berserk for the extra Fell Cleave and change, but this is just napkin math, not trying to go completely full retard on it, since I'm not even sure if the classes share the same base damage multiplier or not, and I don't have a link to the damage formula calculation shit offhand. Point is, neither of them is blowing the other out of the water on the buffs.
Sure, I can do something quick for PLD's Holy Spirit nerf. The Holy spirit nerf is probably the most variable one since PLD's MP recovery can be quite variable between Sheltron usage and external sources of MP.
This is the highest PLD parse on fflogs (for Susano, like the other two), once again limited to 5:50 duration. fflogs.com/reports/PMN6T2hqn4gjL7ar#fight=1&type=damage-done&source=6&start=13813580&end=14165409
In this 5:50 time window, the Paladin used 23 Holy Spirits, for a total of 554.9 DPS.
With the Holy Spirit nerf, the PLD would have lost 690 Potency over the 5:50 timeframe. Since there's no Dark Arts or other shenanigans adjusting the base damage of Holy Spirit, we can do some simple math in this case to determine lost DPS:
- (400/430) * 554.9 = 516.18 DPS after nerf, or a loss of 38.7 DPS. Just a little bit over 1% total DPS (3,493)
It's a nerf, for sure, but people seem to be blowing it pretty out of proportion, much like the DRK/WAR changes.
Assuming we round up to 2% overall damage gained/lost by the tanks, this would put the highest parses (Susano, Player Damage Done) for each tank at:
PLD - 3518.2
DRK - 3339.8
WAR - 3280.6
Even if we push WAR to 3%, it just puts them on par with DRK, and PLD still very comfortably in the lead.
