True, but they are sacrificing their own GCDs to lock down yours. It's no different than a PLD using stuns, a BLM using sleeps, etc.
This is false. SCH/AST can LOS, kite, position properly and Purify. You can even Esuna/Leeches/ED the bind of FA.
Not quite, the healing potencies are actually a bit unbalanced, in favor of WHM. However, AST and SCH are much better at healing themselves while under pressure, something which WHM is very weak at. While I agree that Noct is not in a good spot, it was extremely powerful before. If anything, the only change I would like to see here is an MP cost reduction on AB while in Noct stance.
The first part of this is an opinion, not a fact, and while I won't take the time to sit here and count out the abilities to deny your second claim, I think you need to consider this, as I've stated before: AST/SCH are more effective at keeping themselves alive while under pressure with no assistance from their team.
Except that it can be compared with other abilities...And if you are letting yourself get CC'd for 24 full seconds, you have a ton of personal skills to work on. Also, if you are being chain CC'd like that (without the ability to E/L/ED or Purify or move your keyboard/controller) then the WHM is putting them and their team at risk by wasting 3 GCDs and their own self peel.
Another thing you are not taking consideration is this: If the WHM is choosing to use Fluid Aura offensively (on the healer in this case) then they do not have it for defense, and are extremely open to getting piled on.
