Can we make Aerlion sol instantly cast his q (discussion)

Obviously he is supposed to have the weakness that is clear cut but i feel like not being damaged by his circling stars is good enough. At the moment he can only cast ult on people who are on top of him. I would think that give him something else to do. Giving him the instant cast of q would really help him. Even if he can still cast him q instantly he still has the weakness of getting jumped on. The counterplay could easily be wait for his cd to be down then engage like many other champs. You could even make his cd a bit longer or change it a bit to where it would be ok to be able to cast it instantly. Anivia can instantly pop her q after she fires it but aerlion sol can't. I get the tactic would be a bit unhealthy but i bet riot could find a way to balance it. He has a hard lane phase and the only thing he can do is engage but he flys in with his q being large and he is in the middle of everyone gets jumped on and then he has to ult and run away but he then cant q the people who are on him. I just think that changing his q to be able to be instantly popped would help him extremely well and be a good way to fix this amazing looking dragon to be played more instead of only being able to be played in top elo. He is a really cool look dragon with great particles and controls stars he deserves to be changed and helped a bit so that people can play the champion he is.
