So something that has been rattling around in my brain for a bit is why not make the mounts more useful? If the mount you use effects your hero, even in a minor way it would make them more appealing! I was thinking that maybe a mount could change your special attack so a higher ranked mount could make your main hero have an attack like Rhize or Dawnbringer. Since there are heroes that have better attacks than your main, why not make your mains more powerful based on something like a mount?
