So let horses be able to stash quivers then? When you're running on foot, 1 quiver.
And besides, those shots are "easy" shots where you barely pull the string back. Good for shooting fast but you don't have very little velocity and it has almost no piercing ability. Would barely pierce cloth.
Theres no point trying to argue with him Zapper, you say to him a+b is c, and he will reply W! W! (eg. he replies with unrelated, offtopic shit) He has some very bad tunnel vision, and seems to base his arguments on siege mode, which is pointless since realistically, noone who plays siege more than battle should even be allowed an opinion, its such a boring zerg mode where thought and tactics dont enter into it. One team zergs, the other camps flag, any other plans are fail. Also, hornbow is a horse bow, I'll leave it to horsemen, as I have said before, that bow needs the tag "Only usable on horseback", it tarded that you can run with that massive sheath hung on you.
as to this:

That kid using a 10 pound bow doesnt have a clue about archery, watch his fucking left arm FFS, he has never fired a non-kiddie bow else he wouldnt fling his left hand forward with the shots, doing that would quickly destroy your elbow joint, probably fuck your spine aswell. Loosing a 90+ pound bow is matter of balance and form, you dont spam arrows unless firing into massed groups of infantry, because arrows do NOT grow on trees. Historically, only slingers spammed, and thats because their ammo was either rocks, or if using metal ammo, could be very quickly made since it is a single cast, NOT like arrows, which need 1/ shafts making, time consuming before machinery 2/ Fletching, time consuming for 2 reasons, the process is fairly difficult and you need feathers with also need prep and a bird, and 3/ Heads, which need casting and then attaching. Archers NEVER spammed arrows, they may have fired fast into massed formations, but since we dont have 10k armies fighting 10k armies, it does not apply.
Anyway, back to topic: Longbow needs to be 1 slot, because without arrows it is simply not a weapon, so combined with arrows to be 2 slot. Archers need to be limited to 1 quiver, 27 arrows is enough.
