Is it possible to have an option to trade a hero to lower star hero from same event or same season. Trade 5* hero for 4* or trade 4* hero to 3* from same event or same season.
For example trade 4* Carol from Santa challenge to 3* Rudolph from same event.
It may seem counter productive but I see this game as a card collecting game. I would rather have variety of hero’s rather than high level multiple of same hero.
