For years, people have argued that an instant 20% mitigation is too overpowered when its available at any moment especially when WAR's tank stance, while oGCD, doesnt have its full benefits until they are healed at least up to the amount of HP Defiance gives them. This however has become a very outdated argument as tanks have all received more mitigation options, both internally and externally with things like pallisade, benison, feint etc.
All of the downsides from WAR's Defiance have been answered with Equilibrium (healing the WAR for a little over their new HP total from entering Defiance) as well as Unchained (negating the damage penalty inflicted by defiance). In a nutshell, Defiance is currently the only tank stance that is completely reasonable to use as a tool outside of progression since Unchained allows the WAR to use their tank stance as an actual cooldown with a slight DPS loss due to losing Deliverance's 5% buff and crit buff, as well as losing access to fell cleaves temporarily but instead gaining access to insane mitigation tool that is Inner beast. So with WAR having more or less an oGCD tank stance with little to no downside, why is it that PLD/DRK's tank stance haven't been made into an ability? I don't see any legitimate issue with a tank losing 20% damage for a few GCDs but gaining 20% mitigation for a time. Not only would this make PLD and DRK's tank stance so much more convenient to use for when you really need help on mitigation, but it also affects the play of both PLD and DRK as their playstyles alter slightly while being in tank stance. For PLD, you lose the auto attacks from sword oath and thus lose the 5 oath gauge per hit, but you also gain the option to generate 20 oath gauge per holy spirit if you wish to use holy spirit under shield oath. For DRK, you gain the ability to use Blood price and also benefit from the extra MP gained from using Syphon Strike while also retaining the high amount of damage from Bloodspiller under Grit.
What do you guys think? Is an oGCD Shield oath/Grit too much, or do you also feel like it's time to have these skills become Abilities?
EDIT: For an oGCD Shield oath/Sword oath/Grit, I suggest there to be a recast timer when toggling these stances on or off, similar to Defiance/ Deliverance. This way the stances wouldn't be something you apply on and off with no timer involved.
