i have also noticed obiously how much mana should i have at 70 MM hunter plz pst mana is really beatin me down

do you have a steady shot macro?  I have one that goes autoshot, steady shot, kill command.  I throw in arcane, multi, etc as needed, and at about 50% mana, I switch to AotViper, I hardly ever run OoM in a Boss fight (have 8k mana)
