I'm sorry to those that suffer emotionally because their Brown charm has Blue mastery or whatever.
It is no different than rolling strength on a staff or any other undesirable combination.
Neither change will happen. Your basically asking Paul to put effort into engineering a way to remove content he created because "we want better drops"

You think you do but you don't.
Basic economics
Better items dropping more frequently does NOT magically bring more FG into the game and make everyone rich.
Better items dropping more frequently does reduce the value of all items and all time previously spent.
Wealth is relative and the fact that you can't go out and buy or ever hope for a perfect LS item is one of the reasons why the people that still play are around whether they realize it or not.
The price difference between an item the gets you to MQ efficiently and one that costs 100 times as much is the rarity not the functionality.
