I actually liked Eureka in the end and spent a lot of time at the tail end of Stormblood in there. But it a massive problem and that has to do with hive mentality of the western playerbase: all is fine and dandy if this is actual content but as soon as new content comes out the old content dies. This is problematic as the SB relic is locked behind Eureka. And I can't actually imagine any kind of changes which would make this soloable.
