Would it Break Aurelion Sol if he could instantly detonate his Star?
Aurelion Sol's only means of self-peel (outside of his ult) is his Q, Starsurge. It's an AoE stun that detonates when he reactivates it or it reaches his Outer Limit. However, A-Sol can't reactivate it immediately. There's a short delay, meaning he can't really hit enemies in melee range.
Would it break him if he could? It would make him feel a lot more smooth and in-control of his kit, and would give him some recourse against assassins.
Even if the stun duration/damage scaled with the size of the star (so point-blank stars did a mini-stun, while stars you babysit across the map are nukes), I feel like it would be a big improvement.
