Originally I was on the side of saying "dont nerf this", because its really not that hard, and I think failure is fine in a game. I mean ,we all took several tries to get through the later stages of each Super Mario Bros. level, didnt we? But then seeing how the content after it is easier or the same level, I sense that Shinryu is indeed a mistake and was intended to be more facerolley too. Why? Because the entirety of Omega comes after it, and is very easy, Susano Ex is barely more difficult, and Lakshmi is now old content so doesnt count anyway (she was replaced by O1 freeloot boss entirely)

So I think while I believe FFXIV has gotten way too easy and will suffer for it, Shinryu is, in terms of the dramatism of difficulty, horribly overtuned and should be massively nerfed. It makes no sense to have an actually challenging (for first tries, anyway) fight as a gateway to faceroll content.
