I'm not knocking them, they're fine weapons and I do actually enjoy DR. The grind doesn't bother me, and even though I'm not going to use the visuals for 'em it's one of those little MMO ticks, you know? Fill up the bar. Get the thing. It's fun.
But yeah functionally the weapons are useless. Heck they don't even do anything in the most recent content, NOR any of the most difficult content in the game. They're for epeening measuring contests with logs -- long, LONG after the log race has been over -- or glam/endwalker prep.
