Why do you fail at Hashmal?

[Zojha]

You realise that would make some Savage encounters near impossible right?

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.
