Berserkergang plus Fighting Fury

Is it reasonable to allow a class with Fighting Fury to have Berserkergang on their proficiency list? Should the abilities stack?

I ask because I’m thinking about allowing it for an Orc Barbarian class, and I want some input before I go ahead with it.

Considering it comes with an additional AC penalty I see no reason why not.

It seems fine to me.

Alright, thanks for the feedback :). I think the class will just get the Fighting Fury ability (from Orc), and have Berserkergang on the proficiency list for those that want to focus on that aspect.
