I've gotten into Eureka a bit but an issue I'm seeing is people who can't play much a day may get left behind. We had someone who joined our NM party who started praising us for letting him join because everyone else would kick him out of the party, since irl things made him start Eureka a day later.
I'm on Spring Break from my job this week (when college kids get a break so do I) but what happens when I go back and I can't play all the time? I know people will say that loot is loot and they will do the lower NMs still, but eh.
