I honestly think the HW relic line was the least nauseating. Haven't done ARR and Eureka reminded me of the first mmo I played. It was grindy, if not more so than eureka. My main issue with content like that is it feels pointless, if it had a more compelling and involved story, then maybe it wouldn't be as bad. Or at least had dailies to make leveling more tolerable instead of a seemingly pointless grind.
