Red/Blue buff visual
I was thinking about how they look on the champions (the little symbols around their feet) and began pondering about how they could look better. I found a bit of inspiration in Zenyatta from Overwatch. If you don't know, Zenyatta when he uses his heal or damage amp abilities a little orb comes out of him and hovers above the affect target.
What if Red/Blue buff looked like that? It would be very cool, there could even be a cool animation of the buff coming off the back of the slain creature to indicate who got it in those tense situations battling over who can last hit it.

I thought the orbs in their backs could just hover next to the affected champion, although I'm not sure if it would be too distracting from other effects or be too similar to runaans.
But it would look somewhat like this (excuse my poor paint skills)

Tell me what you think? I think it would look awesome
I'm also not saying red and blue buff look ugly, I'm just saying a cool idea I had
