Personally I would love to see crossbows more limited. Preloaded crossbows getting initiative bonuses at the beginning of combat makes sense. Then either putting them away and switching to melee, or running for cover to reload and fire again.
Same with muskets. One shot at the beginning of combat with potential killing power on critical. After that, you're carrying a club.

Anyone here ever loaded a musket? Anyone here with only average strength or below loaded a crossbow? Anyone fired a hand crossbow (useless)? Anyone loaded a musket?

You'll get one shot then it's time to pull out the saber ;-)
