Divine Divinity made clever use of it in a couple places: One where a questgier asks you to go bring back a specific magical axe from a certain dungeon, and there were FOUR identical axes there.
None of them were the right axe, the real one was hidden.


Another case was an cursed item that drained your stamina when it was in your inventory, but if you hadn't identified it, you wouldn't know what was going on.


In any case, I'm not going to dispute that Identify is usually just a gold sink (really, it basically functions like a tax on the sale of magic items). It's apparently going to be in, though, so why not give the Barter skill something else to do to make it more appealing?
