Suggestion for better clarity
Maybe I'm just unskilled, but the vast majority of players on league are casual players I would think. Not sure about now but I was told at one point that most players out of all players were bronze and silver players. So I think this suggestion will help in clarity to the casual audience. Of course this is just a minor suggestion and not completely necessary but I just wanted to put it out there.
I think one thing to help casual players differentiate between a champion and illaoi's spirits pulled is to make those spirits health a different color. Many times, players on my team as well as myself would spend 0.5 seconds if not longer, hitting the spirit that illaoi pulled from enemy champ. I think if the spirit had a different color of health, it would give clarity to know if you are attack the spirit or the champion. It would give players a faster reaction to knowing if that is a spirit or a champion you are attacking because of the health color difference.
Also, I do not know how this interaction works, but I am hoping that if illaoi pulls a spirit, and I ult enchanted crystal arrow as ashe onto the spirit, would the arrow go through the spirit or would it get wasted onto the spirit? If it is wasted on the spirit, can we make it that ults dont work on a spirit because it would completely act as a body shield to my ultimate that has a 60+ seconds cooldown
