I'm 100% in agreement with the OP. As a matter of fact it's not only the randomness of the loot that pisses me off: it's also the insane amount of magic/unique items that pollute any corner of the game. Finding a magic item every time you crush a couple of skeletons simply spoils the sense of achievement for finding something worthy in a place hard to reach, discourages the use of crafting skills and adds an unhealthy amount of busywork to the game.
