If you are determined with +skill helmets use Harlequin Crest instead as it will give you one less skill but improve combat skills by 2 and give a bigger life/mana boost + 10% DR.
be really good for an elemental ranger. Rangers don't use combat skills (most of them don't, anyways), and if it gets 2 sockets, they can put ias or resist jewels or anything they need in it. So yes, it is pretty good. It isn't quite as good for fanatic rangers, but hey, nothing is perfect for everything.
