I don't know about you guys, but I find most of the helmets and headgear annoying (except for the circlets and wizard's hats). So I toggle them to be invisible -- in both cutscenes and during gameplay. However, the problem here is that whenever you dismiss a companion and they go back to their spot in the camp, their helmets would reappear after a long rest. So once I get them to join me again, I have to toggle the helmets off all over again.
The worst thing that happened to me regarding this is during the ending.
I did not have Karlach join me during the final battle. So during the ending cutscene where she's dying, her ugly-ass helmet has reappeared and was now covering her entire face. So as she lay there crying in pain because her engine is going off and she's about to die, I just could not absorb that powerful emotional moment because that stupid helmet is blocking her face.
So please, I hope this issue would get fixed. If I toggle the helmets invisible, please have them STAY invisible for the rest of the game.
