Animate Guardian vs Righteous Fire...

You might wonder what's the comparison. I'm just wondering why the AG has this annoying little ethereal sound effect when it moves around... while my character is idle by the way. Does this thing have a condition that it can't just still?

Why does a highly popular skill... perhaps even meta... like righteous fire NOT make a sound while it's burning enemies? Even that one unique belt that does chaos/poison aoe to nearby enemies does this little sizzling sound effect. Begs the question... why can't one of the most popular skills in the game get that little bit of fan service... or perhaps I'm the only one that thinks this way.
