Alternative to pavise shield
Crossbow men should be able to equip a stand for their crossbow that offers either no protection or far less then the pavise shield but lets them reload their crossbow about 5% faster reload. It should be movable and/or mountable, but only for crossbow users sort of like a ballista but that may not be a good mechanic.
Stand for crossbow
Faster reload when mounted/or passive reload when around it if not mountable
Less protection then pavise shield
This could at least add some variety to crossbow users and hopefully it won’t be overpowerd.
