if everyone has limited arrows it does a couple of things: it helps from a strategic element where if you run out in the middle of a big fight, you either pull any unbroken from dead enemies or you go melee or magic. Enemies are limited also, which makes them switch tactics and can figure into your tactics also. It should be rare where someone has an unlimited quiver, and even then - maybe that's an item you can get from an enemy at high level. Again d&d and not Divinity so many of the special arrows shouldn't exist at all. And I don't need or want a survival game, didn't advocate for weapon sharpening or armor maintenance - I specifically said arrows. in addition, I don't think fast travel should exist outside of large towns, there could possibly be random encounters, exhaustion mechanics so that short rests and long rests have additional meaning, and short rest and long rest camps should happen where you are at the time like D&D....
