I've been experimenting with different ranging techniques, especially for lower levels. Have you ever tried using a crossbow with bolts? At a measly 2gp per bolt, poor rangers can buy many bolts for a lot cheaper price than that of the bronze arrow. Unfortunately, experience might be gained a bit slower due to the decreased speed of the crossbow (I am not sure about this, can someone confirm?). This method may only be effective until ~level 20 as the crossbow fails in ranged accuracy in comparison to other different types of bows, when by then, rangers would have been able to receive enough income to support using the bow-and-arrow technique. As to your guide, it contains many already known tactics. It requires pictures and more in depth information that the average-joe may not know or understand. Overall, it may prove informational to new players, but that is all.
