Ability Indicator Update
Wouldn't it be neat if the ability indicators previewed the animation of your skill?
I had this idea when thinking about how poorly Ziggs's range indicator works with his Q. It doesn't show how the skill travels or where the bounced land. For new players, it's probably confusing and if you're trying to aim it carefully it can still be difficult unless you're very adept with the champion. But if you could see a ghost image if the spell, you could learn how to use it better.
The same could apply to all skill shots. Most veteran players probably don't even think about learning the skill anymore, but I think this could be a good feature for newer players.
