One of the biggest problems is all the people who say they hate Eureka but "only do it for the relic/hair/glamour" then complain non-stop about Eureka.

Don't do Eureka just for some item or hairstyle. That makes you a number on Eureka's Participation records, showing Yoshi that "People are playing this!" Just don't play it at all.

In a way, those who unhappily play Eureka are part of the problem simply because they help bump participation numbers.
