It's the same mentality with trying to nerf Warrior countless times despite how it hasn't been working at all for years. Nerfing is easy and requires no brainpower or effort, see something good? Hit it with the hammer, it's totally not going to just make everything unfun if not cause problems in the future.
Pretty sure if Healers were called Support there wouldn't be as big of a deal, but much like Tanks are blue DPS, Healers are green DPS since DPS is god in FF14. You can't really convince these people though, and they'll just have to be met with disappointment when this terrible idea isn't implemented, just like tanks in general got even more sustain options in DT in general.
I will say though, I hope DRK players and Healers get some love, but with the ideas both sides spew out(nerfing everything fun when SE very rarely nerfs jobs), I'm not surprised there's little traction there.
