I don't think this is being complained about enough.
Helmets are fux0ring UGLY. As sin. No, worse than sin. Aside from the fact that everyone and their mother, cousin, and red headed stepchild is walking about in Senpai cloaks and helmets (often mismatched- ugh, what fashion taste!), I physically switch away from my helmet unless I'm fighting. Side note, I also have to physically switch my coat and Pioneer Pack, since for some inexplicable reason, you can't wear a backpack and a cloak, which strikes me as odd, since my book bag functions perfectly normally when I put on my coat.
My suggestion to FC: For fashion's sake, please, dear gods, introduce some kind of trippy nano technology that projects an invisible energy field helmet from a circlet or hat or hood or something. Probably for a little less AC than a normal helm, but something that looks nicer. And can be worn with sunglasses. :-p
Or at least a snazzy MA helmet. And cloak.
