I mostly liked Eureka, but I don't really want them to do it again in the next expansion. The main problem I have with it is that they are so good at creating instanced battles and dungeons with scripted content, but they keep insisting on creating this type of grind content and annoying random content like deep dungeon. Basically, a bit of grindy content like Eureka is fun once in a while but I don't want it every expansion.
