Highend ranged troops should b pretty well armoured, such as Sharpshooters, Marksmen, Crossbowmen and Archers. But those below should carry Falchions or similar weapons and perhaps some padded armour and a hood or some of the other light armours.
None should carry twohanded weapons of course, but swords, even good swords should be open to them. And often archers did carry small target or buckler sheilds, so smaller round shields should be open to them too.
I suggest people look into the equipment regular crossbowmen had in the 1300s+ which is the approximate time we are dealing with here. It could get pretty heavy, some even had reinforced mail AND padded armour as well a bascinets.
But right now it really seems the problem lies in the weaponskills of the units, and that they carry big Voulges or Bardiches.
The Weaponskills are just about even for all styles for the ranged units. Clearly they should have no skills in polearms or thrown for instance, while their main skills should be pretty high and a fair skill in singlehanded (though not as good as now). A change of those two areas would have a significantly larger impact than going about and stripping them of armour, which they DID carry. Let them retain the armour, but change the skills (we all remember how 'fast' we were at 60-80 points).
