I think the biggest thing for me is getting that sense of accomplishment. And right now it's lacking for me in the Relic quest chain. It's almost a foregone conclusion that given enough time you will get your next Relic stage completed, so when you complete your Animus or Nexus or w/e stage you're currently on it's anticlimactic. Sure, you're happy to be done with that stage, and have the final product for w/e reason glamour, functionality, or because you're a completionist, but there is also this pseudo buyer's remorse that wonders if it was all worth it, or will it ever be worth it in future stages.

If the content progression was engaging and fun and not recycled and repetitive the end result wouldn't be such a big question mark on the risk/reward scale. I'd more happily settle for a 2nd best or even a glamour only weapon, if the progression to achieve it was fun and challenging.
