Same! At the same time, I felt really shafted over the BLM and DRK one.

The majority of them were subpar. The amount of resources that went into Eureka are considerable and a lot of the relic weapons were just mediocre. However, I don't think they will drop it. Eureka is assisting them in maintaining elevated sub retention levels. They will design new Eureka with feedback in mind on the pitfalls of its predecessors. Its uptake in JP is pretty high. There is a lot of content which they should ditch, but I don't think Eureka will form part of that, and a lot of it is built off recycled assets.
My question is what do they believe sticking to it is adding to the game? If they think it's required to maintain engagement, would they not be better off separating the dungeon and raid release cycles from all the other content in the patch? They are already sort of doing this in how they deliver Eureka updates.
However, there's a lot of content, like PVP, Blue mage, Gold Saucer mini-games and such which see extremely little use, which continue to have resources poured into them. Sure, some people like them, but are they enough to say these expenditures are providing good value for money? Alternatively, if the cost is a bit less gear, is this the end of the world? There have been nothing but complaints over the gear design in SB, and a lot of it is frankly unimpressive. Putting aside the AF sets and some raid sets, I don't think this game is suffering from a dearth of gear anyway.
