This doesn't suddenly make it useful, Tsurumaru, the Delve GKT, easily outclasses it currently.
Where you get the idea that sword should equal GKT is beyond me. Many others before you have already complained about the relative weakness of Relic and Empy weapons, and nothing has come of it, nor do I honestly think anything will ever come of it. They want these weapons to remain viable, but not to remain the best. When a more viable option is easily available from a BC, Skirmish, Delve, or whatever other endgame content they decide to add, I really don't see the reason for even going for these. Honestly, beyond Aegis, Gjallahorn, Armageddon, and Yoichi, I really don't know how/why the market stays afloat. Argument can be made for Scythe too, but the others, you're really not going to see the value out of it compared to what you put in.
They may as well come out and say "stop making (most) Relics and Empys, your crys of 'but I put in so much work!' will not work this time."
