You forgot healer plate and shields.Updated the post even more...man there is just so many things they've changed in 13 years.
Nowadays there's basically 6 kinds of loot:
--Plate
--Leather
--Cloth
--Necks and rings
--4 kinds of trinkets: tanking/healing/melee dps/caster dps
Back then there was:
--Plate for tanking (prot, prot)
--Plate for DPS (ret, fury, arms)
--Mail for caster DPS (elemental)
--Mail for healing (resto sham)
--Mail for melee DPS (hunter, enhancement sham)
--Leather for healing (resto)
--Leather for caster DPS (moonkin)
--Leather for melee DPS (rogue, feral)
--Cloth for healing (priest)
--Cloth for caster DPS (shadow, mage, warlock)
--4 kinds of trinkets: tanking/healing/melee dps/caster dps
--Caster DPS swords & off-handers, maybe axes for shamans?
--Healer maces & off-handers
--Caster staves which I think might have been +damage and +healing, I forget
--Stat-stick agility staves
--Wands
--Melee DPS 1H swords / 2H swords / daggers / 1H maces / 2H maces / 1H axes / 2H axes
