My personal changes to DRK/PLD

[Warkupo]

I'm not feeling the oGCD vibe for PLD/DRK because the damage reduction is instantly applied, versus stronger incoming heals. What I feel like needs to be a change is Sword Oath and Shield Oath need to be on the same button, and be an automatic switch, or to a slight extreme make Sword Oath a constant passive, so your only giving up one GCD instead of two when swapping stances.

You can set this up with a simple macro like

/micon "Whatever"
/ac "Sword Oath" <me>
/ac "Shield Oath" <me>

Granted, they *are* on the GCD so you run into the queuing issue, but you shouldn't be switching so frequently that this is even a percentage point DPS loss. You can also just activate Shield/Sword Oath while the other one is on and it will automatically drop your active Oath for the new one.

Shield Oath and Grit can't be oGCD simply because they are a 20% damage reduction cooldown with no recast timer.
Warrior Defiance can be an oGCD because it is not a damage reduction cooldown. Inner Beast on the other hand is, and is a GCD.

Sword Oath has to be an oGCD, to put it on pair with Darkside and Deliverance.
