I actually really like that in Eureka I can just "do relic".

Like, it's point is to "do the relic". I don't have to grind old DNGS, I don't have to farm tomes that are either outdated by now or were worth something back then, I don't have to do things that give me next to zero reward other than progress. With Eureka, though it has many flaws, you can at least do something different in a new area.
