Would it be possible to add 1-4 past HotMs as featured Heroes at the Elemental Summon Gate with the colour rotation and slightly better odds to summon them?
For example, first week could look like this: 1-4 blue HotMs and 1-4 green HotMs after 3 days. Next week: 1-4 yellow HotMs and 1-4 purple HotMs after 3 days. When the same colours appeared again, then 1-4 different blue HotMs and 1-4 different green HotM would be featured.
Here’s Horghall as featured Hero in this photo. Next time there will be a different green Hero. It would be perfect to see a past HotM as featured there
