Hints at Blue Mage in the level 60 ALC quest?

If they have 100% equal healing to SCH, then they have 100% equal healing to SCH. How, and through which CDs they achieve it is different, but the result is same. Mentioning for example Lustrate is pointless, because that same healing potency would be somewhere else in the AST kit to ensure the same outcome.

So you don't consider out of combat role swapping to be a perk of any value? Being able to adapt to a fight or any group composition is exactly 0 weight in the balance budget? Does it at any point stop being so? If you could, out of combat, assume a stance, that outputs the dps of a real dps class, or a stance that lets you tank as effectively as the tanks, all with the same gearset, would that have to be taken into account for balance?
