sorry if that sounded missleadnig ^
when we charge our weapons we get a sort of blue/yellow circle flashing by the weapon, when it is charging :

the idea is that for those players who have auras, when they charge instead of having that animation ( ^ ) its replaced with the same design of there aura! ;D
basicly you will look badass, more reason to get a aura (:
p.s- i dont have a aura D:
I heard you like auras, so we put an aura in your aura while you use a charge attack so you can have an aura while you have an aura.
