Illaoi is so screwed
Illaoi was already a gimmick-limited champion. Now, though, she is completely screwed.
Before, people could avoid damage from Illaoi by running in circles. Now, Riot has taken it a step further and released a champion that is a hard counter. Aurelion Sol can straight-up kill Illaoi by simply running in circles.
On a side note, if you are using Aurelion, please pay attention to which direction you run around enemies. Compared to standing still with your passive hitting a target, if you run WITH your stars, you greatly reduce your dps. If you run AGAINST your stars, you greatly increase your dps. Another way to put it: RUN CLOCKWISE!
