Timer systems like arrow counting, rations and encumbrance are good for game flow. Removing them tends to diminish the level of emotional investment and roleplaying in the game.

Maybe for a certain kind of game. Survival horror, absolutely - as an aside, i really want to find a good survival horror fantasy RPG, I think that’d be really fun. But for mainstream fantasy games? It doesn’t have the same weight or drama. The question isn’t “Will I have enough supplies for this adventure?”, but “Will the entirety of the campaign conclude before my 100g worth of arrows in extradimensional storage last until I retire this character, or can I spend less?”
