This same Rioter was playing around with an Asol rework years ago as a personal project. I wonder if it will be somewhat similar.
Passive: Something like his current E active that activates after moving straight for a while kind of like Taliyah? Except you have full control of him like Kayn wall walking.
Q: Stand in one spot and breath fire. It follows your cursor and costs mana per second to continue spewing fire. Leaves a burning trail in its wake. Idk what that trail does yet. BTW you can use this ability on towers because star fire melts them in my head and A Sol has a line or something about not caring about them.
W: Live R but resized and re-balanced to be a basic ability. So basically a rectangular Syndra E. :)
E: Create a star at target location that fades away after X amount of seconds. The star can be overloaded by casting Q/W on it causing it to explode and stun people caught in it after a brief delay (E->W them into the star and then burn them with Q).
R: Create a blackhole at target location that grows in size over time (max size after 3 seconds maybe for a size as large as Nunu ult). Enemies in it while it grows are slowed. Reactivating the ability collapses it and pulls everybody and all stars to the center also making them explode.
