Would be nice to set up a “defense team strategy” that would default your defending heroes to target certain types of heroes or target specific situational elements.
Either a team strategy that is very broad such as:
-Target Healers First
-Target Flanks
-Target Lowest HP
-Target Elemental Opposite
Or for more in-depth AI strategy, you could select a specific behavior for each hero.
-Tiburtus - target in order, center - flank - rear
-Lianna - Target Lowest health
-Kageburado - target healers first
-Joon - Target Hero with most mana ( special activated first)
Something along those lines of being able to select default targets for your defense to strike.
I’d probably limit the targeting to special skills only.
