TLDR: We do not plan to do mass releases of heroes/monsters such as wave 1 and wave 2 in the foreseeable future.
We receive a lot of queries from players concerned about how often we will do mass hero releases, like we have in our wave 1 and wave 2 Kickstarter campaigns. Our current plan is to make wave 2 our last Kickstarter campaign for Judgement. From this point forward we are planning on releasing 1-2 hero/monster miniatures per quarter, so around 4-6 a year.
As a games company we are conscious of what bloat can do to a game and don't want our game to go down that path. We also want to keep the game accessible to new players, something that too many heroes, too soon, would make very difficult. Our main motivation to do the wave 2 Kickstarter was to release the wave 1 heroes that remained unlocked, and to get enough heroes /monsters in the game to provide the depth and variety the game needs.
