Why do you fail at Hashmal?

It would - To be more precise, it would make every healing check that is based on the current strength of healers impossible, because the strength it's based on is gone. That's like having a fight that requires a silence and then removing silence from the game.

No big issue if it's just "one" fight, but the entire game is plagued by that.

Still no big issue for a vertical progression game like this, because you can fix that going forward without touching old content - You simply ramp up the health/VIT scaling. 20k healing on 20k HP is a full heal, 20k healing on 200k HP is only 10%, 40k damage on 20k HP overkill and 40k on 200k only 20%. It's uglier than going for a one-whole approach, but it's quite doable.

But then you mess with the HP checks and tankbusters we have as well. No point fearing Halicarnassus's Critical Hit if I have 200K HP as it'll hardly hit me for more than 70K already without cooldowns.

The best solution is what Ameela said, make every other content turn up the damage a notch.

You're messing with it, sure - But you're messing with it every single time you upgrade a piece of gear, every even patch when the iLvL gets raised, every expansion when unsynced comes along.

I see no issues "messing" with old content so long as it doesn't make it impossible to clear, it's old content. And if you go min-iLvL for the challenge? Well, you'll get your old HP values and properly fear that mechanic again.

In case you misunderstood: Ramping up the health scaling means newly introduced items get relatively more VIT to gradually increase the gap, not that you suddenly give every item thrice as much VIT overnight. New items already give you more VIT, they already make old mechanics lose their sting, go back into O1-4 at the end of SB and you'll have an easy time seeing as much (or just run some unsynced coil for the lulz). You simply accelerate that process until healing is relatively weaker.
