A pass on creating a projectile system for Melee would save a lot development time. Maybe the resulting rangedlessness could be tested globally in cRPG beforehand. Ranged looms might be replaced with funny hats or nothing at all. Most likely the latter.
So funneh...
Real issue is extra bonus to effectiveness ranged classes have in Warband, while shieldless have none. Of course, that is historically accurate and pikers/swordsmen were filling up gaps shielders left them when progressing forward but it kinda hard to emulate that in cRPG/Warband for various reasons. One of them is shielder class being inferior and overall design of shield combat mechanic in Warband. Because it is one button blocking system compared to 4 directional for shieldless infantry, to compensate devs have put many maluses to shield combat, making it slower, clunkier and overall more boring. If M:BG devs could solve that piece of puzzle, at least one aspect of this issue will be fixed and we'll see more proper teamplay and formations.
Ranged works just like they should formation wise, they can take higher ground for extra damage, have siege equipment at their disposal which shields them from cavalry and other ranged, can kite, can spread and kite. As their number number grow their effectiveness becomes much greater. None of that goes for other classes, not even shielders benefit much from their shieldwall.
