Eh, there's a lot good in FFXIV, and most of the complaints aren't new - they're things the game has been doing since AT LEAST SB, and in many cases, since HW or even ARR. People are finally just feeling they're getting stale, but in Human norms are...a bit prone to hyperbole. That is "The game's been doing the same thing for 10 years and it's worked pretty well, but is getting stale, how about mixing it up?" is less click-bait than "The game now sucks and is going to die if Dawntrail doesn't do a complete turnaround!"

...but the former of those two is more accurate. The gearing, patch content amount, content amount in general, encounter design, trend of Jobs over time; all of these have been going on since 4.0. Some since 3.0 or one of the 2.X patches.

THAT.
SAID:

What I said above is still accurate; it's gotten stale.

To their credit, the Devs are trying to mix things up, in fits and starts. The PvP actions, the whole PvP system for that matter, and Criterion Dungeons are all attempts to mix up and experiment with different things. They're doing it, of course, alongside the fits part - SGE being a near carbon-copy of SCH, dungeons still being hallways of 2x double packs + Box repeat x3, and a slower patch cadence that also dropped Exploration Content this expansion in favor of IS/Criterion, and poor reward structure for Criterion - but they are doing it.

As for what changes need to be made: Depends entirely on who you ask.

I've literally seen some people defend the 2 min meta, something that I had previously thought was universally hated.

.

But one of the Yoshi P interviews talked about changing up rotations, it sounded like he was saying DT will have the stuff we had here but also an Exploration Zone and something "new" that we've never done before, etc. I'm waiting to see what the next Fanfests and the Media Tour reveal, since that will set the tone, but I do think it's time to shake things up a bit, and it looks like we may get a bit of shake up, the question is just how much of one.

(Also: There should be nothing other than Ultimates that REQUIRES Savage gear. Though it does seem previous tier Savage gear should be the entry level for the next tier's Savage, with Crafted being a side-grade (same ilevel, different substats) for people to spot fill slots or gear an alt Job, as opposed to a total replacement. But that's just me.)
