Perhaps I should add here that if someone's looking for something specific in a quest what's to stop them from spamming astrals each run? I mean just having re-rolls available with reaper-mode screams exploit.
Run a quest on the highest reaper you can trudging through the muck for however long it takes, then spam astral re-rolls to maximize the odds with maybe a +named item boost.
Sorry, with drop-rates the way they are (generous) I don't see ransack penalties as needing to go away anytime soon.
