Here it cooomes... my MMO obsession >.<
Sulley -> Tank (Templar/Guardian/Warrior... whatever you like
Mike -> Magic DPS (Sorcerer/Mage)
Randall -> Physical DPS (Rouge/Thief/Assassin)
Celia -> Support (Healer/Cleric)
Sulley is strong, Randall can use stealth, Mike, the little Green Mage... This thought just came.
