Lantern of Arimor Suggestion

So the lantern is gone. Good. Only thing i really miss about it was the occasional buff to monster rarity and quantity modifiers. I've thought about you guys implementing it in the future like an endgame extra juicing feature.
You open the map in the map device and prompted to a screen like before but instead of different monster types just leave them as normal/magic/rare/unique monsters and grant them a percentage modifier of rarity or quantity(devs choose what numbers). Also remove the bad rolls of just making the map harder. Make the reroll a button that costs gold increasing with each try of rerolling hoping for a better modifier. In my opinion this will be a good endgame grind, hoping to get extremely good lantern rolls on a very well rolled t17 map, also it can be a good sink of gold besides the auction house. Keen on seeing what you guys think.
