Give the possible Eureka 5.X its own weapon, and separate Relic from it

[Lacan]

Considering you can go through the entirety of Eureka without upgrading the weapon a single time or what have you? It's so obvious that they took a Diadem design, realized that in and of itself wasn't enough going by actual Diadem numbers, and then put there the biggest carrot they could find.



It'll make the place nigh unplayable once it dies down and people are basically alone in there.

I don't think that's the case. Eureka in FF III was specifically a place where you went to get the most powerful weapons in the game, and the Eureka storyline in FF XIV is literally about a primal/eikon capable of making weapons of legendary strength. It's obvious to me they built Eureka as a place to house the new relic weapon, but they didn't make it mandatory to progress so that you wouldn't be locked out of the new zones because you didn't care to make the weapon.
