is there a way to see the list of characters that we own?
Hello! For now it's not really possible, I am working on a companion website that would allow players to see their stats, their hires, etc etc.
Some things you can do to mitigate that issue for now are the commands !missing (displays 3 units you are missing) and !freehire (automatically hires a unit you don't yet own, recharges every 50 wins)
