And you're so convinced that you know what ressources the Dev Team should put into what kind of content that you're willing to ignore :Does it not puzzle you, even a little ?
- Eureka was described as a niche content
- Eureka mechanics makes it clearly not likable for the majority
- Yoshi-P has stated that he was suprised by how much people actually tried Eureka
- Yoshi-P has stated that, as a director, it's important for him to experiment new ideas, even if some of them might not work as well as expected
- Yoshi-P stated that is was important for him to redirect ressources to these new types of content
- Another niche content, namely PVP, constantly receives new updates, including new maps, new rules, its own ranking system, its own gameplay, its own actions and its own adjustements.
Which is still irelevant, since, again, no one forces you to do something you don't like, and that some people like challenging content for the adrenaline rush, while other likes FATE farming because it's not as stressful. So maybe you should use the logic of "Don't like it ? Don't do it"
Considering that the "fact" is how difficult it would be for a newcomer to clear past zones to reach Hydatos, easily finding full instances in fact completely negates the issue.
Except that past relics didn't have the same purpose. In ARR, relic was the casual powerful weapon, and the way to keep old content alive. In HW, Tome weapon was made available even without raiding or waiting for the catch-up patch (First hint), Wondrous Tails took the burden of keeping the old contant alive (Second hint), and there was longtime complaint that the Relic didn't receive its own content since the very first iteration (Third hint).
Come Stormblood, the relic got its own content, doesn't have anything to do with older content, and is in no way competitive for new content. So, bascially, you completely missed that Heavensward slowly shifted the purpose and the target audience for the relic and you still cling to what it was in ARR.
Again, Eureka was not marketed for the wide audience, you just assumed the amount of ressources that should be placed in a niche content, and deduced from your assumption that Eureka then must be made for the majority, without any actual info on how far Yoshi-P and the dev team would go to experiment something new, and even when every official statement clearly said the opposite of your assumption.
