I know there's options, and your latter statement is only half-right.
I'm not upset about there being options, I've already done those paths for multiple relics. (pvp, hunt trains, etc). However, you are current in me wanting a grind I HAVE to do instead (a la field zone and/or open world methods). I'm an mmo player who loves large-scale content due to the social nature of MMO's, relics served as a conduit in field zones and fates for everyone to get them that way, but that is not here this expansion. I liked feeling the achievement of getting them on top of being able to repeatedly go back into said content for more for X or Y reason. I need goals without shortcuts.
