They won't lower one's price that has been bought by many people.

Bamboo Rod has always been 7 damage ever since the EC shop was released, it was a very decent weapon that many favored.
The first reason why people want it to be buffed on damage is because of Cotton Bud that made it look weaker/lousier.
Now katana is comparing to bamboo rod just because it is 9 damage?

I really have no say for this because the reasons are just there.

As for Hyrule Dagger, Mace & scimitar. None of those weapons were ever faster than katana/saber.
They're all 8 damage and same speed as kiwi/Hunter. In no way was it nerfed, it has always been that way even in the release.
