why is asols passive still viewable when hes in bush?

Whatcha asol spotlight. It's intentional.

Surely it's also to do with the idea that it expands outside of a bush, so you could be next to the bush slowly dying without realising because he's in there hitting you.

This ever happening seems unlikely, but you know.

Because the old passive interaction caused several bugs that made you see his passive on different location than he actually was. I remember one competitive game (don't remember exactly if it was LCS or even worlds) being restarted because of that.

How do you hide a space dragon and stars in a bush? Too bright XD

Edit: on an off note: I think once Cho'Gath gets a few stacks, he should no longer be able to hide in bushes either lol

for counterplay, imagine sol being able to hide in bushes and just stun ult w combo people ?
