Now this data is not mine (all credit goes to reddit user krainz) but this gives an overview of how popular field content and its closest EW equivalent is for people who are included in the branco census
In general here is the main points
-completion rate of abyssos normal is 45% of active players
-acquisition of the mandragora mount for IS is 16% of active players
-percentage of 70+ that went to pagos is 35%
-percentage of people eligible to enter BA is 19%
-percentage of players that went to Zadnor is 47%
-percentage of players that got to resistance rank 25 is 34.8%
-MSQ completion rate is 70%
So from this we can see that Bozja specifically but even eureka have great retention rates, 32% of people who unlocked eureka reached BA, over 50% of people who unlocked Bozja reached rank 25 and this is compared to an MSQ completion rate of 70%
I’m still not sure how square saw these numbers and thought people didn’t like field content but I think it’s pretty definitive evidence that field content is popular
