Need to address the Eureka in the room.

it wont hurt the game, [...] sacrifices little.

I dunno if I'm remembering right, but wasn't a patch delayed because of Eureka near the beginning months of Stormblood? Ever notice the players complaining about each expansion containing less and less content?
Imagine how much better ffxiv would be if the team working on Eureka would instead work on content that the community unanimously enjoys.
