Just a small tip where I used to go and farm for signets, gold, potions and cloth – go to Firewing Point in Terokkar Forest. The mobs here respawn in groups of 2 in under 5 minutes and drop around 10-30 silvers as well as Firewing signets, potions and cloth. It’s an added bonus if you’re with Scryer too.
Note: In some servers, this place is crowded with people and is generally overfarmed. It’s a good spot nevertheless if you are on a quiet server
