Right, but that's why I pointed out the stat squish. The stat squish would make players WEAKER in the content vs stronger. Their answer to that was basically they made an algorithm that adjusted damage and health of enemies down to scale it as well. Moreover, they wouldn't have to redesign all content anyway, since ARR and HW content was already designed with that healing model.
They also wouldn't need to change things like Cure 3 - spam Cure 3 and you don't do it long because MP is a constraint. The issue is that oGCD heals need to be weaker so you use them to augment GCD healing, not replace it. And if you have more frequent damage, it's weaker. Say you have 5 hits of 15k damage 5 or so seconds apart. You need to heal during that since waiting until the end means some players would die. Using mitigation will only cover some of the hits. So you have to fall back on GCD heals. In the current game, you get a single hit of 60k damage, have to use a mitigation to survive, then take no damage for the next 45 seconds, so a single oGCD from both Healers will top the party off.
Smaller but more consistent damage actually forces the use of GCD heals, since even if heal potencies aren't changed AT ALL, you would need to space that healing out more, and you only have so many oGCDs.
The second step would be to weaken oGCD power, since people can still heal with GCD heals, but they're limited by MP. Doing this also works fine, since it means people clearing ShB/EW would be entirely able to do so using the GCD healing kits. As we ALL KNOW at this point, players can clear most content without touching a GCD heal, even Savages, and apparently, even Ultimates. So weakening oGCD heals but leaving GCD heals alone would mean that they couldn't just oGCD heal the pain away and actually have to use GCD heals. But since the GCD heals are still relatively powerful, it means the content can still be cleared with no retuning. Run an Expert Roulette or Extreme Trial right now and use no oGCD heals, only GCD heals. You can probably clear it just fine as long as you know when to back off damage so your MP can regenerate (and...maybe not even that). If that's possible, it means no old content would even need to be retuned.

EDIT:
How do I live in your head for such cheap rent?
Like, who even ARE you? I've never seen you post in replies to me until now, but you're hugging my butt across multiple threads, lol
Seriously, just drop to your knee and give me the ring already. It's clear at this point you can't stop thinking about me. XD
[For the record, I do Extremes all the time - which is "end game content/playing the game", and occasionally Savage if I feel like PFing for it. I have a variable enough schedule I don't have a Static, and I don't want to try clearing P3S or P7S/P8S/TOP without a Static, it's that simple.
So I do "play the game" and am very familiar with mechanics and gameplay. NEeeeeext!
Also: It better be a big fat rock on this ring you're giving me to justify all the stalking~! <3]
