Boss/Enemy Hero Drops: Unique or Randomized Items/Weapons?

[stupidface]

I was just thinking that it would be quite a good feature, especially for replay value, if, in the expansion, there was neat loot that you could nab from enemy heroes or bosses that you defeat.

For example, the Krakken might always drop an awesome harpoon - or, alternatively, he might drop either the harpoon or a dwarven diving helmet or a mysterious necklace. Likewise for enemy heroes, though of course their items would be less powerful.

I think that this would be a good incentive to try to beat bosses and enemy heroes earlier instead of waiting until they are easy, and the randomization of loot would also give some replay value.
