"War by the rules"

Tournament rules: 1. Games are played on the HoMM V: Tribes of the East 3.1 version. The game is played on the Ubi server or through the Hamachi program. 2. Game settings: Difficulty – Hero Turn time limit – 8 minutes Animation speed – maximum Fast battle – enabled Simultaneous turns – enabled Dynamic battle – disabled Ghost mode – disabled Autosave – enabled ------------------------------- I have a question: what does it mean to have "fast battle" enabled? Do you only fight using fast battles? And do you also use fast battles for hero vs. hero battles? o_0
