The new raiding meta is making me want to quit.

not only that, didn't Yoshida deliberately nerf one of the new EX dungeons because it was too taxing on the healers? I seriously think that he doesn't have a proper grasp on the difficulty of healing in this game, since my healer friend is able to do the new EXR while texting.

Or your healer friend is just a good healer. I believe in one of the interviews, they said that they playtest the content by going in on classes they aren't familiar with so that's probably part of why things ends up so scaled-down.
