I hope they leave savage alone. You don't need hundreds of groups clearing it. You won't need to clear A4S to access the next tier. Beat A4N to access the next tier, and savage will be unlocked as well.
As I've said a few times now, the problem with just having savage "as-is" is that you don't have the equivalent of Coil this time around. Normal Alex is not coil, it's Crystal Tower/DR Trial level of difficulty, meant for mass consumption like any of the story content. EX Primals are the next step up, then Coil and the first half of Alex Savage. Then there is the second half of Alex Savage and Savage Coil. In HW, we lack a comprehensive Coil tier to satiate a larger percentage of players interested in end game content. They're not quite the critical mass audience the majority of the content is made for, but they're also a significantly larger base than the .1% elite progression groups. This demographic is likely your long haul dedicated players who stay subbed and have very high activity/playtime.
And moreso than before, A3S and A4S are heavily gated (read: reasonable chance of clearing) to 99.9% of the player base by gear checks that don't apply to the .1% (Elysium, Lucrezia, etc) as indicated by the fact they've now cleared all of Alex Savage. As I said before, Alex Savage was, IMO, designed as a screw you to everyone because the designers felt like their work was cleared to quickly and were in probably in a continuous discussion/debate about how to make it so the best of the best couldn't clear their challenging content so quickly. It was a pride thing, IMO. We got A3S and A4S as a result. The devs also gated and removed other options groups were using to circumvent the challenge, ie pentamelded crafted gear. If they refuse to add another difficulty tier to Alex Phase 2, they should re-evaluate their design choices for the next set of raid bosses and maybe tone it down just a little bit on the back half if they want more people to try it and remain actively engaged. But again, I insist they should make a third tier in between Normal and Savage...
I don't think there is anything they can do right now to fix this. We're stuck until 3.2, though I seriously urge the developers to reconsider their approach to progression by introducing a middle tier meant for a larger portion of the players, the more dedicated base that wants to keep playing a lot. Keep the savage mode to reward and challenge the best of the best and give the game some sort of prestige, but be sure that you're not turning off a majority of your players from the game or being more active because you catered to a very small, but very vocal base. Case Study: The downfall of Street Fighter for almost a decade thanks to Third Strike (catering to the most elite players to appease them while alienating most of your fan base). You can say Third Strike was an amazing game, but it came at an extremely high cost.
So again...as I've said numerous times...have three tiers for whatever the next phase of Alex is called. Alexander Phase 2 (meant for a majority 75-90% of the player base), Alexander Phase 2 Hard Mode (meant for a larger part of the fan base 25-50%, and Alexander Phase 2 Savage (meant for a small portion of the fan base, 5-10%). This ensures that you have content relevant for as many people as possible while providing appropriately incremental difficulty options to keep as many players engaged and actively playing while delivering a sense of accomplishment. This also means re-evaluating the reward system. Perhaps something like gear from lower tiers that improve your overall stats so you can challenge the next level might not be the best course of action for rewarding your player base, or at least, shouldn't be the only one. Perhaps unique gear sets (both stat and appearance wise) only drop from savage, so the only way to get this cool looking set is by trying to clear it. And more than just the lame dangling carrot of "you can dye this version!"
But if they're not going to offer this, which is a realistic possibility, they need to offer more content aimed at the target group I described above as being the "Coil" tier. Either add in more EX primals or something. And stagger them a bit. Perhaps we get an EX primal every two months instead of waiting for a new one every patch? I don't know, that might be unreasonable to ask of the developers, but having more EX Primal content in a steady trickle could alleviate some of the negativity and frustration being expressed right now.
Edit: I acknowledge this could also be more a sign of me getting burned out on raiding and or FF XIV in general, so this is strictly how I view events since HW. Which means I could be totally alone in my point of view.
