To be honest I used to have some of these opinions, some I still agree on like the overworld/zone design, homogenized job design and boring equipment, but I learned to just appreciate what FFXIV does have to offer. These days I only play FFXIV for the story, new (but otherwise short-lived) battle content and social interactions. The game doesn't completely fulfill what I wanted in an MMO but it's still enjoyable.

I would be surprised if FFXIV drifted from its current content roadmap and significantly changed the fundamentals in the next expansion, especially this late into its lifespan.
