We have the beloved exotic item tax so why not a more sophisticated dynamic arrow&bolt tax? If there are more than - let's say - 20 players on a battle server it's business as usual with 20 or less percent of the players being archers or crossbowmen. But if the amount of ranged is higher than that threshold the projectile upkeep grows exponentially. While the tax with 30 percent shooters would be still affordable, 50% or more will be a financial nightmare for them. There could be a nice warning message that goes like "Due wood scarcity and greedy fletchers the arrow/bolt price went through the roof. Better use a two-handed sword like a real man instead!".
