A new feature should be added that allows the user to define (or use some predefined) concede rules. For example, I don't wan't to waste either mine or my opponent's time by playing a game where the health difference is too big and I won't have a lethal. Here's a possible example mockup: Code: concedeRules.add("missingLethal and enemyHero.Health > 20 and (enemyHero.Health - ownHero.Health > 15) ");
