I like how Aurelion Sol's kit is simple most of all.
Passive - Simple aoe. Q - Skillshot into stun. W - Makes passive stronger. E - Idk about this one, but it's not super overloaded or unberable. R - Simple skillshot that knocks back to peel and then slows.
He has a simple and seemingly unoverloaded kit that still manages to be intriguing.
Glad we don't have another Ekko, Kalista, or Yasuo.
