Lets stop fighting SE and work with them. What are your ideas?

But this is not only a problem with FFXIV

There are multiple problem in this game. On this problem, I won't even judge SE on weher killing this meta is good or bad, even if I don't personally like it. But the premise of the OP is "Ok, it's pretty clear they want to do that, how can we contribute so that the final result is still enjoyable" instead of "Let's keep manifesting until they back up".

Which is kind of weird. Imagine if healers' healing output and damage are scaled off int, and their main stat is pie, I'd bet a lot of them will wear int accs after having enough pie to heal certain contents.

Yes, you could say it's weird, but it's tied to a pointless stat inflation. Basically, they should remove PIE and VIT completely, making HP and MP scale only with your level and your job, and adjust MP cost and mitigation with those.

If, say, Samurai could only need on, and eventually wear, VIT accessories, then would that make VIT their "main stat," or would you say that there gameplay indicates otherwise?

If Samurai was only able to wear VIT accessories from the get go, you wouldn't even ask yourself which accessories to use, so it's kind of moot point, especially now that bonus points have disappeared.

For me, the simple fact that your amor increases your damage output is a silly choice right from the start...
