[2019] Beserk Talent

10% increase in weapon damage for 10% armor lost. If i have a shotgun hitting for 100k and i'm out of armor, whip out the shotgun for a last minute shot, it should be a 200k hit. Has anyone seen it work? An smg hitting for 10k and half of my armor gone it should hit for 15k. I have it equipped, but really havent seen a big difference in my damage.
