I feel heroes are too hard to upgrade, not because of cost, but from the amount of time they are gone. After level 14, each level takes a dreadful week, and there are 40 levels! They need to be decreased to 2 days, that way you can dedicate time for just hero upgrades, instead of waiting a week for a tiny upgrade. If you agree or disagree, give me feedback, I'd love to hear it.
