Battles on airships are quite original and unusual for Heroes: there are different types of these ships, with varying cannon power. During a battle, one ship launches a platform that troops can cross. There are also cannons that fire shrapnel grenades during the battle. You can either board the ship or destroy it, and the hero inside will survive (teleport). I was also thinking about adding air tanks.
But the battlefield will be incredibly large.
I would like to know your opinion on this idea.
