The only issue Elezens have with helmets/hoods/anything that covers our ears is that there’s only one preset to ear length. Meaning, if you make an Elezen with short, stubby ears, when you put a helmet on it’ll default to a long, pointy ear. It’s one the main reasons why I don’t wear helmets, although hoods aren’t too intrusive. I wish I could show you an example, but I’m at work .

Edit: derp, didn’t read Antonio’s post before making mine. I’ll keep it here to +1 his gripe.
