Final Fantasy Tactics A2: Grimoire of the Rift/Thief

Thieves can be a great help for your clan if you're desperate for gil or in a financial crisis. With their abilities that can steal gil, items or loots they can help you. They have good speed and evasion but the other stats are average. This is also required to have the Ninja job with the incredible Dual Wield ability that allows you to equip two one-handed weapons.
