All DPS classes use a set of priorities to deal the most efficient damage in any given situation. SMN is really not that hard to play. Just don't let your DoTs fall off your target(s), manage your pet properly and know the fights. The difference between an amazing SMN and an average one is how well he/she can manage their pets and keep their DoTs up on their target(s). Knowing your class is half the battle and knowing the fight is the other.
