If only saving expansion from largely pros is prob then a simple token for pass which can be purchased with different coins like
1 pass for 5 elite cryo coins / 10 cryo coins/ 5 drag tooth will be enough to divert farmers to whole content and unloading new maps and their contents.
Peoole still love to farm elite king while ignoring maus only for fangs and elite runners.
If coins are paid enough farmers will grind other maps
Addition:
Make Km3 alive or Norder Mines and save all maps
