Define that please, cause "Aura" is, imho, not a clearly distinguishable line.
Are you counting Shurelya's? WotA? What about Frozen Heart and Abyssal? All four can be built with non-Aura goals in mind, and the last three aren't even seen on supports all that often, compared to other champions(Shurelya's is often seen on tops and junglers too).
Do these items disappear, or do they just stop being Aura-like, turning into something more individually beneficial?
