Could be usefull for other players
But it kind shows off that you have an aura i mean then what is the point of having aura then if nobody can see an not even yourself
I would agree if they made it so that you cold see your own aura Its just then Its worthless having an aura (but that my opinion)
But still i kind of agree cause other auras can be annoying from times to times
So i would say

People can still see it if they have the option turned on some people find it more annoying than a nice thing to look at but others might see it the other way round so that's why their is a option to either have them turned on or turned off
