There is nothing wrong with the relic quest honestly. The problem is the reward is not worth the effort.

As for the content. They are trying to mash a game with multi-class system which is usally reserved for a sandbox style mmo with a WoW style mmo which was designed for single class per character and alts.

Aka the content is designed for an alt based mentality, but the class system is designed for a everything on 1 character design. The first one is the problem in my opinion not the latter.
