I feel like people are really trying to sell Bozja as the incredible engaging piece of content that every loved every minute of when the reality is a lot of people did it for the relic because they just liked it better than the other options. The reality is both it and Eureka are FATE grinds with the setting changed and some extra bells and whistles added to it. Going into Zadnor now (I haven't been to the southern front in a long time) you just sit in the top of the map running the same 3 or 4 FATEs until a CE pops. There was also a time not very long ago the getting CLL to fill was near impossible before they ramped the mettle rewards up to insane levels, and that was necessary for relic progression so anyone looking to do it was just plain out of luck.
