So, on throwing rebalancing.
Throwing should be the ranged skill most affected by wind and other weather conditions.
Make weather have potential to make throwing less accurate, deal less damage, how you’d make this work specifically is up to you, but there’s not nearly as much force in throwing to keep simple things like wind from diverting the accuracy and damage, especially with high volume items.
Making throwing a less reliable works-anywhere, anytime skill would make it’s use in combat more fair, but obviously this would not wholly solve the problem, as it would still exist indoors.
