I am not seeing how this helps the Devs.
You could change it so during Challenge events the matching color Bosses are effected.
During Challenge events reflect yellow event, all Season 1, and Season 2, stages with a yellow Boss give +50% loot and are -1 World Energy and a unique enemy would drop colored coins, 100 coins would allow a Challenge event summons.
During Challenge events reflect yellow event, they would drop yellow coins that could be used for the Guardians summons.
1.12-9 has a yellow Boss, so during reflect yellow ( Guardians) it would be +50% loot, 3 we and a chance of a clockwork mob that drops yellow coins for use in the summons.
This seems boring.
Maybe they could add a hard mode just to the Elite mob stages?
As a reward, the first time you complete them it gets a silver Daily summons token for normal and a gold Epic Hero token for hard.
Completing 1.23-6N would give a silver Daily summons token while 1.23-6H would give a gold Epic Hero token.
Completing all Season 1 hard stages would give you a Commander Grey avatar.
I respect you, so I will not move this to #ideas-feature-requests
