Actually if you go back to some of their early live letters / interviews Yoshida stats that the Relic weapon was supposed to be the casual equivalent to the Savage weapon. Where the Savage weapon takes skill and teamwork to acquire power, the Relic took time time and patience to get the same level of Power. In ARR and HW I could keep upgrading my Relic weapon and never needed a Tomestone or Primal weapon. In SB however I've had to keep getting tome weapons since I can't stand Eureka. There has always been Crafted, Relic, Tomestone, and Savage weapons for Endgame. Deepdungeon weapons if you want to add catch up weapons. Eureka should have been another weapon added to the list of options. Not taking the place of one.
