I have every hero that has been available to me except Wraxius. There are so many of them and most of them I don't use, I just max their command for my army. I'd love to be able to favorite or star heroes so that I don't have the scroll through all of them in a battle.
At the same time, I have different item builds for my heroes depending on what kind of battle they are going into. e.g. sometimes I max Jacques might, sometimes I use the +1 mech buff item. Sometimes I just have all my heroes with max command if I am training troops. I'd love to be able to save these builds as presets. It would be even better if I could pick the preset from the battle screen (assuming the items aren't in cool down which they usually aren't).
