It could be both a solid helmet alternative for nimble frontliners and an entry level helmet for others. Less protective than nasal helmets with coifs but much lighter(less fatiguing).
Right now planning equipment for a dodge/nimble build is a pain specially because of shields and helmets. Shields I understand(they are fatiguing to use indeed), but there should be a hard helmet alternative that doesn’t come with a -5 to -7 fatigue penalty. I don’t mention body armor because Paul already showed the high end light armor variations coming in the expansion. Also in theory having a viable light helmet is more important for a nimble build than armor(unless you waste a perk point on “steel brow”).
