Another possibility is to set it up like a training ground, you go in and select which hero/heroes you wish to include in your formation, you then select a hero/heroes to fight with certain abilities, runes, saintings, etc.. etc... So you are not facing a specific player and could try working on say a bloodstorm vs bloodstorm or vampyra vs rhize etc...as a way to learn how to best set up your formation against another's formation based on their heroes to create the best outcome. It would be a rather large interface to construct, but one I would really appreciate and a great way to spend time in the game where you would otherwise be standing around between events.
