Default Quick Cast is NOT a Solution!
Relatively recently Yasuo's Q's received a relatively un-common special treatment...
It received an automatic quick cast setting due to the abilities frequent use especially late into the game.
This is a PROBLEM. And has been for quite awhile. Because of this type of treatment, some skills such as Cassiopeia's Noxious Blast HAVE NEVER RECEIVED AN AoE INDICATOR.
Currently 10 Champions now have received this special treatment:
Ahri's Spirit Rush
Cassiopeia's Noxious Blast
Fizz's Playful and Trickster
Irelia's Transcendent Blades
Karthus's Lay Waste
Riven's Broken Wings and Valor
Urgot's Acid Hunter
Vayne's Tumble
Yasuo's Steel Tempest (first and second actives)
Zyra's Rampant Growth
With that said... I understand why many of these abilities are smart casted. But until this happened to Yasuo I never realized how badly this negatively impacted my experience. Normally I like to aim my skills without smart cast in my spare time to get a good feel for the range and size of abilities before I smart cast them to ensure that I use the skill properly.
However when Smart Casting was forced upon Yasuo's Q, I could no longer do that and it made playing him fairly tricky for me as I couldn't feel out the range of his Q like I usually do.
BUT WAIT! I have a solution... well actually. Riot does, their just not using it.
Also relatively recently, a UI change in the options menu left us with nice little "smart cast" toggle buttons below the skill keys. Which allows us to choose which skills we would like to automatically smart cast. However because of the nature of this system being a GLOBAL setting... The majority of players seem to have them all on, or all off to eliminate confusion. Or change them at the beginning of every game.
Riot has the ability to make these settings Champion Specific. If they just take the time to implement it. This would also allow them to create DEFAULT settings, which for characters like the mentioned above, can keep the same default settings. While still giving the champion designers the ability to implement proper targeting reticles for skills which still to this day, do not have.

PS; The Flash Summoner Spell is another interesting case which I feel should come to the same conclusion
