It really isn't this, though. Have you see this thread:
https://forum.square-enix.com/ffxiv/...mplex-DPS-kits
You posted in it, but have you followed the discussion?
A lot of those people aren't posting in this thread - I can't really blame them - but are healer players talking about how they don't want complex DPS kits, they want to do more healing. Many of them seem not to want any more healing buttons at all (another coin in the "Ren isn't alone" bucket). None of them are arguing for healing to be braindead. Quite the opposite, they want healing to be the part that is challenging.
I know your opinion there - but novice healers won't be able to clear 4 mans - yet this is what a lot of healer players want. Besides, we can keep 4 mans as braindead as they are now, "but we'll be bored"; you'll get over it, there are other ways of grinding tomes. Regardless, it's clear there's a hunger for healing kits to be what are more interesting, not damage kits, and for encounter design to be changed. A lot of people there are saying what I do all the time, that the solution has to involve encounter design changing and giving people more opportunities to heal.
Feel free to tell them they're wrong, I guess.
