I'll clarify what it changes then. Balance is not and has never really been a particularly significant issue with the healers, and isn't relevant to how fun they are, but that's what SE focused on. It wasn't asked for, but it's what they decided to do. Accordingly, the healers are boring and thus in a broken state, but balanced.
They did not try to fix the healers.
There is no indication that they were or are going to try.
There was no opportunity cost to be paid to fix the healers because that was never on the table and hasn't been publicly mentioned.
They tried to balance them - in the simplest possible manner I should add, by making them very similar. And they got a resounding success at the expense of making fun jobs.
This of course might be an artifact of the official translation, as it's just one word, but if the word choice of 'balance' in the English media was faithful to what they intended to communicate, it is telling.
