If I remember correctly, Thief's steel mechanic in Final Fantasy XI was very, very inefficient when utilized upon Bosses. That said, what they could do with the Thief is make their Steal Mechanic operate in a manner like this:

Instead of stealing actual physical items that you can use to convert into profits. Instead they steal temporary items that can be used to generate buffs, debuffs, or to heal the player. Some other games in the MMO Market have already implemented a system very similar to this, so its not like it would be a groundbreaking system to implement the steal mechanic in such a manner.
