That alone shouldn´t be a reason to not use scale: the mongols even used lamellar as neck and throat protection. Even with maille coifs, if they are to be of real use, they would never be just hanging losely to not be hindering head movement, but in fact be backed by some padding underneath against blunt or pierce damage. Most movies depict only a hanging aventail or neckcoif, but that is as useless as only maille as head or body protection without padding.
Also, with armour you will never have the same full range of motions as without.
