Besides the storyline, I just use Bozja to level grind. Once you get to Lv71 and are able to enter it, you can get a class to Lv90 relatively quickly.

But yeah, they also have relic weapons and armor. I don't really bother with that stuff though since it's so time consuming and tedious. And I'm assuming you only need stuff like that for high-end content anyway (or glamours in the case of older stuff), and I don't bother with that either. I got my DRG relic weapon, augmented it once, then called it quits.

It's definitely worth doing, though. How long it takes is really up to you. Not sure how Eureka works since I never went back after unlocking it, but with Bozja, you start at "Rank 1" and gain a specific kind of experience called "mettle" that lets you increase your rank up to 25. You get mettle from taking part in the Fates scattered around the zones (you unlock more zones as you raise your rank), and the story progresses when you reach certain rank thresholds. There's a couple dungeon-like instances where you party up with other players in Bozja at the time, and those are time consuming but give you a lot of mettle.
