Point 2: Also regarding the Conflux.
Perhaps it would make sense to add a 300% difficulty level for those who don't have the opportunity to play online but want truly challenging tasks?
For example, at this difficulty level, the rules could block the construction of upgraded creatures or level 7 creatures in the main castle.
Or, for example, mines could yield resources twice as slowly for the player.
I understand that it sounds like nonsense, but these are just some vague thoughts.
