Nope. Daggers are cool. I'm sure a lot of people would like to play daggers but they don't, for the same reason that people don't use katanas. I'm always asked by new players "so where can i get a katana?" but the next day they're running around with a heavy greatsword. Because heavy greatsword isn't cool and not so visible within the pop culture but effective, katanas not so much. "player preference" aka statistics is an objective indicator, "i played since MO1" is a subjective one.
Listen. I've honestly been pretty polite. It's clear you disagree. So let's just leave it at that.
Also, people do use katanas. Literally know someone in my guild who does and prefers them.
