I would like to see new hero attack patterns besides AoE, splash, hit 3. There are a few exceptions like chain attacks that can hit multiple enemies, but only randomly.
I am thinking of those scenarios where the tank is gone and you need to clear out the two pairs left standing. Having a strike 3 or splash damage hero special ready to go is not exactly ideal.
How about an attack that hits only the wings or only the flanks? That may be too specific, so then what if the attack skipped every other hero? Or, the attack could hit the target+neighbors and then skip a hero and hit the next.
Some if these patterns could involve random aspects, but wouldn’t have to.
