¿Por que no los dos?
Nobody on the dev team plays a healer. All communication about healers from Square seems to be from the POV of the healed, not the healer.
At the same time, they genuinely don't seem to understand how their approach to encounter design paints them into a corner when it comes to healer design. They don't know how to properly balance healers because they're working from knowledge of WoW-style healing and trying to apply it to FF14-style scripted fights, or because Square's left hand (the job design team) has no clue what the right hand (the encounter design team) is doing, or both.
This ties back to the fact that nobody on the team plays a healer, because if they did, they'd quickly recognize that tanks had some of the exact same boredom/homogenization issues before Square caved in and made them Blue DPS in ShB. At a minimum, you'd think that if somebody on the dev team did play a healer, they'd report how boring it is to play the MSQ that way. They don't know how to design healers because they don't play healers in their own game, so they don't understand what the role needs, in order to be engaging given the encounter design in the game.
