I'd like to suggest either opening Alchemy and poisonmaking up to all classes or adding an updated potion vendor to the guild lobby. Due to low populations, players who do not play shamans or rogues can't access sought after potions and poisons and the potion vendors in the realm of Norrath do not sell potions or poisons which are highly sought after, potions like Distillate of Skinspikes or the various weapon poisons like Spider's Bite.
