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.
All they need to do is tweak that as they already have the feature implemented. Some containers no matter how many times you reload have an extremely low possibility (if they do at all) to result in anything but common items (ie ham, wheat, cups, etc...).
They can still keep their random loot style and just categorize the types of items that can be present in any given type of container.
I think they know that already though and the way that you see it now is as is intended. /shrug
