Give PLD In-Combat Raise? (3.0?)

[Cabalabob]

I would like the idea of a divine oath but i would tweak it in the sense that it fairly increases the potency of cure, applies regen, increases the enmity generated by healing spells cast under oath, and grants an additional 20 potency attack for each action taken while it continuously drain mp. it automatically deactivates when you're out of mp.

This kind of goes beyond the parameters of the idea, if you want to generate enmity you use shield oath, if you want to deal damage you use sword oath, if you want to recover health you use divine oath. Only thing that would fit that picture would be increasing cure potency, and with the magic damage and MND swap I don't know how necessary that would be. Your cures would definitely be weaker than a white mages but you'd probably be getting more out of them than a BLM or SMN does.

My line of thought was OGC, but they could retain a cooldown as short as the global cooldown or shorter. Mainly just so i can weave a stance change between actions. They'd still be readily available, but are far less intrusive on what I'm doing. They also wouldn't share a cooldown, so switching to Sword oath would put it on cooldown, but Shield oath is already ready to go when I want to switch back.

This would unbalance the oaths. Defiance is off GCD because when you turn it off you drop your health by 25%, turning that off and on again you need a cure to make up what you've lost. If a PLD could dance between sword and shield oath within 1 second they would lose a portion of the "penalty" that comes with swapping. On GCD if you swap to sword you're stuck in that stance for at least a GCD where you're 20% more vulnerable. If it was off GCD, you could swap to sword, spirits within and rage of halone and swap back to shield before the mob even knew what hit it.
