I think I'd rather spend 500 hours in eureka than 500 hours in say normal dungeons. Imagine how much people would hate bardam's mettle if they had hundreds more runs of it left to go for their weapon. So in that sense I'm glad they made new content rather than sending us on a massive farm of old content. Yes there are many flaws in eureka but experimentation and iteration may eventually lead to content that most people like. I think eureka went over better than diadem, maybe next expansion the side content will be something good based on lessons learned from this patch cycle.

The thing that keeps surprising me about eureka is how many different ways people keep finding to be rude and selfish and problematic. Some people who don't need crystals any more have started going into instances just to cause problems for people who are still farming, like pulling far and reseting an NM that was almost dead so we wasted our time fighting it, or entering BA alone and sitting there a while to prevent ovni spawning again for people later because it counts as a BA run already in progress. They just annoy people because they find it funny and negative attention is better than nobody giving them attention I guess.
