You'd probably get similar results for any content in the game.
If you asked about crafting, potd or raids or dungeons I expect you'd get similar replies.
The middle response tells very little and cannot be counted as negative or positive - I answered there and I don't hate it, it's fun with a good group but not my favorite content. The zone is very nice and I wouldn't mind seeing more areas in future patches but the mob grind could be a lot more engaging. I like some things and dislike others.
Eureka has some big flaws but its not terrible and I prefer this to another snooze mode expert dungeon that is only really fun the first time you run it because it is tuned way too easy for current gear level.
