How I would change Aurelion Sol

So after some games with , I have gotten a feel for his kit, but I feel some aspects of his kit are a little lack luster, what I would do to make his kit more interactive is this Passive - minion execute gets stronger as you level, maybe 5 extra per level Q - Reduce the base stun at rank 5 to 1.5 sec, but grant additional effects based on how far its travelled (these do not stack) 500 - stun duration up by .25 sec 750 - stun duration up by .50 sec, dmg increased by 25%, MS up by 5% 1000 - stun duration up by .75 sec, dmg increased by 40%, MS up by 10% 1250 - stun duration up by 1 sec, dmg increased by 60%, MS up by 15% 1500 - stun duration up by 1.25 sec, dmg increased by 85%, MS up by 20% 1750 - stun duration up by 1.50 sec, dmg increased by 115%, MS up by 25% 2000 - stun duration up by 1.75 sec, dmg increased by 150%, MS up by 30% Dmg continues to increase by 25% for every additional 250 travelled at this point W - increases MS by 2% per rank (10% at rank 5) while active E - Reduce the stacks that fall off when taking dmg, rather then losing everything at once R - This ability feels fine as it is, but maybe reduce the Cd by 2 sec per rank every time a star hits a champion

Give me your thoughts, but I feel this would make kit more interactive and fun to play (in addition to giving a reason to charge Q other then more range). Still enjoy this champ regardless though, love his design as a champion in general. Thanks for taking the time to read this post
