Please no more Eureka!

[Reynhart]

If you are coming late to Pyros then you will have a problem.

Not for the weapon. At worst, you might have a problem getting the armor, and only for Logograms dropped by heated box.
And that without even using Logos actions to kill mobs, mainly the Reflect to wreckhigh level sprites.

I've had one person describe Eureka as FF XI effort for nowhere near the XI reward.

Nowhere near FFXI effort too.

For the record, the very first incarnation of a Relic weapon require more than 10000 Ancient Currencies. At best, a good Dynamis run would initially drop around 200 currencies. But, those currencies were sellable on the market board, entry required an Item that cost 1M Gils and between 40 and 64 people. So basically, once you dropped the Currencies, you frequently had to buy them back from your own Linkshell. Aside from that, you could only enter in Dynamis once every 72 hours and the Key Item was destroyed upon entering, meaning that you had to buy a new item even if you completely fail your Dynamis run.

Fast forward several years, the entry Item is now a permanent Key Item that cost 50k (Unless you do a quest that grants permanent access), monsters are still level 75 compared to level 99 characters, and there is a proc system so that doing a specific action/Spell/Weapon Skill ensures single-unit currency drop rate, with a rare white proc that ensure 100-unit currency drop. After seeing that, there's no reason Eureka can't be made soloable in ShadowBringers.

There is absolutely no chance that they'll make Eureka soloable. They will let it rot. FFXI has horizontal progression and the relic weapons from Dynamis stayed relevant for all those years, there was a reason for them to make it more accessible. As soon as Shadowbringers drops Eureka is going to be nothing more than a place to get glamour. There's no reason to make it more accessible. And the devs almost never go back and adjust old content in FFXIV, if it takes more effort than slapping the echo on it or cramming it in a roulette then it's too much work for this dev team.

Before knowing that unsynced would be a thing, you'd probably have said the same thing for the Zodiac. And even apart from being able to solo every content this weapon required, HW saw several tweaks as to make the Zodiac easier to get.
And even if they don't unsync Eureka, it would be very easy to make every item buyable with a few Poetics or Seals, allowing for everyone to have the Glamour they want.

Eureka instances scale with player count anyway. When its nearly empty the NM's actually pop quite fast and still die at relatively the same rate. So in a way they've already made some preparations for people moving on with content. I mean we popped and killed Pazuzu with 14 people in a dead instance that was no longer repopulating and did Penny with I think 26 right before the maintenance.
