Yes the ember caves is excellent Take time to go to the Citadel as well Fun patrol area where minotaurs spawn...fun way to get practise with and level up fusion rifles Also if you have a friend that plays destiny...go and farm with them...actually farming in a fireteam is a great way to knock off patrol missions and farm because one person can pick up a beacon and when the mission is completed it counts for all of you and spend the glimmer you get on ammo synthesis for the VOG.... :)
