Last time I checked, no one in EQ was held at gunpoint and forced to buy potions they didn't want. True, this potion is worthless to a Ranger after lvl 15, BUT Rangers are the only class with Archery Mod spells, but are NOT the only class that can hold the bow. My guess is that these potions are just for Rogues/Warriors (et al) to experiment with, to see what a real bowshot is supposed to look like ;) Last I checked, Sow was a spell only a few classes have, but anyone can use those potions, I assume this is the same way.
