At the risk, to repeat some previous posoters and probably get flamed because I raised a new discussion about it...

Is this new kind of Relic-Quest going to be permanent? If so, why? What was wrong about the old system?

You were able to pick up the relic quest, do it at your own speed and it's not only you or players on your level who benefits from it. Doing the duties several times (especially when you are focusing on a tank or heal relic) makes the queue shorter for those duties. Also doing fates give others the opportunity to level faster. And yes, it still sucks and its still time consuming, but at least you can help others out when you do the quest.

Eureka is the "selfish" Version. You are instanced and you can start the quest only with 70 anyway. Bound by a quest, not helping anyone because they are lower than 70.. did SE really thought this through?
