How about this one. Give each hero in the game stats all the way up to 5*. Then, create a building (you can only have one) that elevates the * rating of heros. So, let’s say I wanted a 5* Bane. It’s crazy, crazy expensive, like 1.5 million food and 7 days wait for each increase, but I put him in and he comes out as a level 1, base ascension 4* hero. Then I have to level him all the way up and I can do it again to make him a 5*. It would take a lot of time, but would be freaking awesome to see some of these lower level guys actually have a shot at meaning something. I mean, who wouldn’t love to have a 5* Derrick?
