Eureka is a kind of content that heavily strays from the rest of the game. It takes a huge turn towards oldschool systems with its grind and penalties, things I've seen people ask for (no idea why, but then again I'm not into this kind of grinding myself). Making something like Eureka was already a risk, quite noticeable by the ruckus it has caused.
Eureka (at least, Anemos, never stepped into the new one) is literally just the same hunt zergfest we've been used to since 2.x, in a new zone. Let's not unnecessarily sugarcoat things.
