I just wish they get their time sink stuff out earlier, Eureka as much as you hate it was dished out in 4.25 in ShB ... Bozja was 5.35. Its strange to me why the relic grind gets moved back so far.
Anima weapon was 3.15 and Relic 2.0 (i believe). give us stretched out quests instead of pushing them all onto of each other. When the 24man raid coins are giving you the upgrade item for the weapons 5.15(?) it should give the quest to get the relic weapon the same level as the raid tier, at this point the raiders are done with the tier anyway. But looking at the trend we will now get the Relic quest at 6.4 with 2 stages.
The ShB weapon was good for a SINGLE raid tier and even then the ilv did not line up and it was overshadowed till the final step. Relic grind and the additional Maps like Eureka and Bozja or Deep Dungeon (to an extend) are huge time sinks, they get out way to late and then cut them short however.
Bozja defiantly has a cut 3rd zone the entire main plot is resolved in field notes ... show, dont tell.
