I don't think there have been a thread where people talked about their favorite tier gear for EVERY class. If there has, sorry. Anyway, I will start out:
Warrior: Tier 11
Mage: Tier 11
Warlock: Tier 8
Shaman: Tier 3
Priest: Tier 11
Hunter: Tier 11
Paladin: Tier 10
Death Knight: Tier 11
Rogue: Tier 8
Druid: Tier 2
Whats your favorite Tier gears for the different classes?
