enchant quivers....
all the quivers in the game have a minor enchant on them that makes them summon arrows, this enchant is just a 'COSMETIC DESCRIPTION" which means its not really doing anything it just makes the whole unlimited arrow thing lore friendly.
when u buy a bow u get a quiver with it (or maybe they sell separate, can't tell which unless I see the actual inventory and mechanic) when u equip a bow u have a quiver on ur back (or side) and thus lore and fan are satisfied and u don't have to ru to town every few hours to get arrows, u have ur trusty enchanted quiver with u
IF quivers are in fact separate (like wow pouches before) then this enchant is inherit TO ALL QUIVERS IN THE GAME with no exceptions, also they can be different kind of quivers like deadric, glass, steel...etc now if this effects the actual dps we still can't tell, but if u look at skyrim u can see that each 'arrow" has a quiver of the same type:

all in all whatever the system is the whole "zomg arrows are unlimited I r pissed" argument can be solved with this simple work around, thus preserving lore, immersion AND it will look great

problem solved be at peace everyone
