I looked at some comments of the mod and noticed that some people said that a few swords were unbalanced in the early stages of the game.
Can anyone confirm or deny this?

Oh btw, I'm talking about the Distribution and balance plugin.

Well I used it with mods like ASIS and Economics of Skyrim which pretty much delevel the world. So if you do happen across a weapon that would have been slightly OP in vanilla Skyrim it would be pretty balanced in my game set up.

Vanilla likely but with mods i use such as, asis, deadly combat and deadly dragons on master difficulty not at all.
