Eureka is such good replayable content
I have to disagree with that. A mindless grind isn't 'good' in my opinion. Adding a billion steps to a relic weapon just to make sure people take months to get one isn't good just because it takes a long time. Eureka is just a chat room (if you're playing on release) with grinding mobs and fates.

I can respect veterans that have little to no backlog though wanting something to keep their attention for longer period of times though, but I'm not convinced that a mindless grind is the solution. I guess I just play mmos way more casually though. For me, raids and a grind aren't why I play FFXIV at all.
