What if Sol's passive was invisible from bush until it hit an enemy?

I mean, Riot said that he was pretty good in the jungle, but being unable to sneak around in bushes really hurts this play style, as well as roaming in general. If nunu ult and other abilities can be invisible in bushes, Aurelion Sol should be treated similarly right?

Having it be invisible until it damages a champion seems pretty fair, and would immediately communicate what was happening to the opponent to avoid the legendary 5 sunfire evelynn experience.
