less items more modifier tier

what with all the spam of garbage items in a typical map; I've often though that what I'd really like is map nodes that gives like 90% less item quantity and +100 modifier tier, or something like that, obviously the numbers would need tweaking. Just something so that I see a lot fewer items but the ones there are a lot more worth picking up. Ideally that could be taken up to 3 or so times so you can get really scarce but worthwhile items eventually when lesser thinsg just wouldn't cut it.
