We recently updated some heroes to address balancing issues and implement some player feedback. Details about those changes and our design goals can be found here. We have seen your additional feedback and would like to touch on some of the concerns that have been brought up. But first, thank you all for sharing your thoughts and helping us to improve the game!
We believe the best option for the long term health of the game is to make large changes quickly, until we have reached a better foundation, and then settle into a slower release pattern for the long term.
While this is still true, we don’t plan to do large updates in the middle of a season going forward, to reduce the disruption of your mid-season progress and event rankings. Bug fixes and smaller changes may still be worked on throughout a season, but larger balance-focused changes, if necessary, will be released only at the start of a new season.
Additionally, we have seen your requests for a feature that would allow you to reset a hero to level 1 and get some of your Ooze back. We agree this would be a positive addition to the game and hope to work on that in the future.
