I imagine that for helmets to work, it'd take a ton of extra work to accommodate the ears. If only limited existing headgear work to start and then any new gear is made wit the new races in mind, I'd be fine with that.
Of course, I tend to only wear glamoured headpieces anyway because my character has pigtails and I hate any gear that cuts off my hair...so this headgear issue won't effect me much. As long as we get the effects of having it equipped, I don't care much about if I see it.
