I am level 54 been playing since close to the release. Over the last few months of playing I have recieved 0 new heroes with which to upgrade or progress. All 15 lvl 60 heroes are maxed out. With nothing left to do I am forced to find something else to do with my time. I have played pretty much all hero collectors available on google play just avoid these games they only lead to waisted time and money. I have already invested into the game because I thought it was fun, this is not.
