Cover should be a Role Action

[Seraphor]

Cover is already incredibly situational for PLD. I don't see how that would be any different as a Role action. It would either be unecessary, or essential, and I don't want to have to Cover people as a DRK or GNB.
I'd rather they didn't make more job skills role actions. Certain imbalances between jobs are perfectly acceptable and Cover is one of those. DRK can TBN the other tank, GNB can cast HoS and Aurora on other players, and WAR has Nascent Flash.

I'd much rather they enhanced PLD's identity, by giving it an ability (shared cooldown with Spirits Within perhaps) that deals more damage as your HP decreases, the classic 'Minus Strike' if you will.
This would interact with Cover in the OT role, as you could Cover, take damage, then use Minus Strike instead of Spirits Within.
Essentially you're making SW/MS a part of the rotation where you need to discern if you HP is closer to max or closer to zero and you can make use of Cover without negatively impacting your SW use, as MS would be an alternative.
