Loot as a +correlation between difficulty & time spent that happens automatically! and innately!

My biggest issue with the game is how towers and tablets work, and the tediousness of what you must do outside of actually running a map that comes as a side-effect

When you do a map, any map, the next map, the previous map, I think you should feel like you are getting the most you can loot-wise from that map no matter what. Linear scaling, positive correlation among time invested, difficulty, and loot, all done AUTOMATICALLY. Time invested (player level and total end game maps already run + their difficulty) allows the difficulty to be increased, difficulty being increased allows better loot. Player no get headache. Player pew pew and buy better gear.

For example, I'm level 92, I have good enough gear, I've run X number of maps already in end-game... it would be AMAZING if these factors dictated what loot I received as a player. Very roughly (I have no idea what these numbers would actually be but it would be easy to figure that out with the proper data), level 92 + 80 end game maps run (difficulty of these add to the score in calculation) = max map available = tier 12 = 102% item rarity & 25% item quantity by default for every single map of that tier. No other loot multiplier stacking. No tablets. No rarity on gear. Just that. Just what you have innately from what you've already progressed through in the game, on that character, up to that point in time! Scalable to level 100, then further scalable with amount of end game maps run/bosses completed and their difficulty, then further scalable by something the players set for difficulty.

This would be my dream for the game, because then I can play the game and everything just works itself out. I don't have to worry about trading for certain tablets and wondering if I'm going to get a return for that investment. Don't have to deal with the tedious trading system just to run maps that are worth it. I don't have to run "worthless" maps just to carve out 3-4 towers to have decent overlap. I don't have to worry about the map prefixes being optimal. All of that makes continuing to progress through the end game unbearable for me currently.
