I don't agree on missile speed not affecting damage, speed has always affected damage. (For as far as I know)
Also, with more missile speed (compared to last version), faster reload and more acc than an arb a heavy xbow, with less str req is way better. As it frees up a point for extra WPF, which means I can reload even faster.
Compared to a heavy xbow, an arb is pretty useless now.
And I can run away faster. Which I'll need with these weak melee weapons. Let's be honest, having some Power strike doesn't turn a Flanged mace into something strong.
Though having archers with an awkpile and other strong weapons isn't really balanced either. Maybe fix the req for a bow to be good is the way to prevent all the STR archers.
