hmmm switching 3rd and 4th doesnt make a difference lol, the balancing part is the units > hero stats
if units too strong , hero cant kill
if hero too strong , units cant kill
if skills too strong , units cant kill
if items too strong , units cant kill
therefore you gotta do the heros first then match the units strength to the hero.
You did be pressing crlt + f9 many times during the balancing process :3
