Pass along that difficulty spike for levels 20 on is beyond comical. It really does make the game unplayable for 2 days a week. I get they want you to work for the 250 gold but under 1000 you are getting very poor rewards for the rest of it compared to higher levels and Nightmarish/Legendary never have lucky versions for the last 2 days. I would rather a 50-100 gold top reward + the other meh ones and it actually being doable not having to smash my head into the wall on Wed/Thurs.
TLDR
Drop the gold reward to 50-100, keep the other meh rewards as is and tone the difficulty modifier way down under 2000-3000. Start incrementing from there.
