Honestly, the entire relic weapon system feels like some small niche of die hards somewhere screamed: I want my old school grind! And then the developers decided to throw this in there. I wouldn't be bothered by it so much if it was more designed around some tough fights you need to bring three buddies along with to complete or something along with a good quest chain built around pushing your class knowledge to the extreme. Right now this is almost pointless to do.
