New to the game. Weapon balancing…?

I played this game when it first came out and now I’m coming back to play some more. Games always been fun! Still is very fun! But I’m curious what the community feels about some of the weapon balancing. Why am I getting 2 shotted by a sword that swings incredibly fast? Seems like some stuff is just crazy good compared to other stuff. Maybe I’m missing the counter play to that? Lemme know!
