Should there be more visual #clarity on whether or not an enemy spell provides vision?

Currently Illaoi's E reveals stealthed targets but doesn't put eyes above their head. Should it put eyes above their head? Having never played Illaoi before, I had no idea that enemies had vision of me until I got a very rude awakening as Twitch when a random Illaoi E hit me.

This same complaint applies to several things like Anivia's Crystalize (Ice wall), Gragas's barrel roll, and many more. Short of memorizing every ability in the game, there's zero indication if an enemy's probing skill that missed you gave them vision of you in the bush or not. Some abilities, like Hawkshot, or Phospherous bomb make little sparkles. Maybe the little sparkles could serve as a general purpose "Enemy has vision of this location" tool.

I am absolutely not advocating that stealth wards make the little sparkles, or that any other STEALTH effect reveals that it's providing vision to the enemy team, or any effect whose center is inside of a bush or obscured by the fog of war, just clarify to the enemy what your skill that they can see does. A new player has no idea if Jayce's Q, fired into the bush, tells them if there's a champ in there when it misses or not.
