Things that could make Aurelion Sol better
Before downvoting me to oblivion, it is obvious some flaws on him :
- Lack of burst except if extremely ahead
- Slow star rotation ( early game is not that noticeable, but later it is ). I think the rotation should increase with AP, but not that hard.
- High CD's since he is not good with cdr items ( Q cd is 10s at all moments , and the CD only starts after the core ends ). and 120s early on into his R.
Can see only this flaws. Also, the 25 below health minion execute is kind of pointless.
can get you halfway to 40. Hell, you could build
.

for instance would get you 30cdr if it bugs you that much.
