What are your first thoughts on Aurelion Sol?

I actually like how his mechanics look so far, though his ult sort of looks a bit underwhelming compared to the rest of his kit (to the point I think it should get away with a cooldown as low as lux's ult). I think what I like best was after looking at the concept art for Ao shin's kit and noticing that they were pretty much the same abilities Sol has, which really cements that he is pretty much Ao shin 2.0 with a cosmic theme instead of a storm theme.
