Ranked by item level, then quality, among items with a known source: gear nothing drops, sells, rewards or makes yet (raids not yet open, the client's test items) is left out. The class filter keeps what the class can equip at level 30 (armor type, weapon skill, Dual Wield, the item's own class limit); the side filter drops items that only the other side's vendors and quests offer. Source: the best known drop first (a Forever rate at 10+ loots, else the vanilla 1.12 chance), then vendors, quest rewards and the profession that makes it.
Other slots: Held in Off-Hand. Every slot and level.
