Hint#2 Stuff orks between the pillars so ogres don't slip through, Put reflects behind to avoid snotball splash on towers, Make sure Mages are far enough back they don't get melee'd.
Hint#3: optional DJin/Imp summoner
Afk Next to LT stack as boost summoner with APP and HUNT, flash heal as needed for the auras (flash heal will reach East auras as well if built correctly)
