u use the flag keep reseting places till u upgrade and put high units and titans in ur units bar and put the strongest heroes 1 high hp melee 2 ranged then watch the battle and move the ranged to the back and control the melee meatshield....alot huh?XD
beast masters should be with warriors,rogues should be with archers,and the necromancer and the wizard should be devastating enemies to both of them together as far as i know
