Simple, the current system is socialist in that everyone has an equal chance for a fair share of the loot, regardless of effort involved.

Also way to ignore the second half of my post. Thing to remember is really dungeon loot doesn't really matter. At some point you should be spamming AK for tomes anyway and it won't take long to get all of the AK gear you will need which will be replaced fairly quickly with DL. And all the gear from every other dungeon will get replaced even faster (with the obvious exception of coil).
