Idea for an Aurelion sol change.

So over the past few days, this idea has been floating around in my head and I have decided to share it to get the communities opinion on this.

So currently, Aurelion sol's Q grants him 10% bonus movment speed while the stellar core is traveling, and I can see the reasoning behind this, with the way his q works, it allows him to create a larger stun radius which can help a bunch in team fights.

However, in certain cases when you need a quick stun (Maybe an assassin/diver is closing in on you, the movement speed dosen't really help all that much since the star dosent last extremely long before exploding.

So my idea is as follows; cut down/remove the movement speed on his Q and give him some movement speed while his W is active. This would allow him to have a chance against certain assassins in lane, by keeping his w active, he could outrun them and keep them out of his no-no zone much easier then he can currently.

Opinons? Thoughts? Suggestions?
