But DRG wears heavy armour.

Chain, they wear chain.

So far we have 4 armor classes, which I'll name as thus

Plate: 100/100 P/MDef. Fending. Paladin / Warrior / Dark Knight wear this.
Chain: 70/50 P/MDef. Maiming. Dragoon wears this.
Leather: 60/60 P/MDef. Strking/Scouting/Aiming. Monk, Ninja, Machinist, Bard wear this.
Cloth: 50/70 P/MDef. Casting/Healing. Casters and healers wear this.
