What am i doing wrong?

Hello.

I'd like to ask for help on how to improve my map crafting to have a better chance of getting desirable currency drops. Due to the nerf to quantity i've tried to pivot into putting more rare mobs and stacking as much rarity on the map as possible.
My current average t15-16 map looks like this: https://imgur.com/a/vEDYtyo
I have around 130% magic find on my gear and am only running water and swamp maps if whenever possible.

So far i've mostly been getting normal regals, exalts and perfect aug-transmutes.
Divine grade currency drops once every 5-6 maps i run usually.
