THIS!!! Other relics you could almost make progress on in the background as you did other things, or at the very least you have multiple options to achieve an end. There were annoying steps, of course, but the fact that Eureka is the only way to progress this relic is very annoying, even if Eureka weren't terrible. Sad I won't leave this expac with a relic, but oh well. I hope they don't repeat this for 5.0.
