Tank Fixes

[MurasakiAeda]

An offensive gauge spender with an effective cooldown of 7 seconds is the last thing Paladin needs. It would effectively make players avoid Sheltron and add so much empty APM as to make Dark Arts seem like a good mechanic.

I feel like removing Dark Arts was a waste, could they not have improved upon it? Like increase it's recast time to something higher like 15s and changes to which abilities could be enhanced by it. There was just too many moves which could be enhanced by DA in SB. Dark Arts could also enhance defensive abilities again. I feel that the issue with DA in Stormblood was how frequently one had to use it, not so much the ability.

At the crux of its core, DA was a 140 potency OGCD. It enhanced every offensive move basically the same way; giving it 140 potency.
Flood of Shadow/Edge of Shadow operate the same way that DA did at the crux of its core; using an OGCD that pushes out a certain amount of extra potency. Only FoS & EoS cost way more, thus solving DA's issue of being required to essentially be spammed.

If DA were to ever come back again, it would need an entirely new effect; as EoS & FoS have taken over its old role.

As far as the OP's changes, you'd have to re-work WARs entire offensive kit if you want to make FC & Decimate OGCD, as you'd utterly neuter IR which composes a ton of WAR's damage. Also 10% all damage reduction for 6s >>> 50% parry. When they're making a bunch of steps to letting CDs be all encompassing, creating or changing CDs to only affect 50% of damage types (only physical or only magic) is a step backwards.
