Its pretty unrealistic that arrows which embedded themselves in a stonewall can be pulled out and used again. On the other hand its also unrealistic that you cant pull arrows out of soft, fleshy corpses to use them again. Evens it out I'd say.
Doesn't really even it since you don't have 50% accuracy, and there's more arrows that miss, than arrows that hit.
IDK, it'll make archery more useless.
Ranged builds are only useful so far as they have arrows, what would my 1 bodkin quiver longbowman do if he couldn't pick up arrows? We'd probably end up with more arrows in each quiver for ballance.
More useless ? Okay, to start, archery is not useless.
Second, you can pick up quivers of dead archers. So even if you only spawn with one quiver, you can shoot more than what you started with. Wich is already interesting.
Or you can consider changing your equipment depending on the maps, like a lot of players do :
-melee comes quickly : 2 slot bow, 1 slot arrow, 1 slot melee weapon
-melee goes in circle, i have time to shoot and to pick up decent melee weapon : 2 slot bow, 2 slots of arrows, 0 slot shitty melee weapon.
Bringing only one quiver, (even more of bodkin arrows) , totally makes you less usefull as an archer. Then again, if you're bringing a 1 slot melee weapon, it's your own fault.
