It would be really nice to have a mini game of some sort in the game, that you could earn maybe coins, or occasionally diamonds or maybe even stamina. Even if it was a small amount, you would find more people playing the game more often. I frequently run out of things to do but still want to keep playing and chatting with my guild.
2nd feature, please make it so we can “spar” our own heroes so we don’t have to constantly ask friends to post a lineup I love sparring to work on new teams but hate asking every 2 seconds
