IMO They will either streamline the relic, or introduce a new questline for a new relic. Based on past MMO's, they will need to as outleveled content becomes empty. As for the people who will rage as they had to do all that work, that's nothing new, people rage daily for no good reason, or the same reason over and over. It wouldn't be the first time a MMO has done this to their relic questlines as new content comes out, and in turn makes everyone who put in the hundreds of hours prior very upset, but dev's only look at the majority, not the minority.
