OKay but real question, why is elise's stun so good

Disclaimer: This is not a rant or anything ragey back to the topic at hand Why is elise's stun just... good its slow as hell, its hitbox is fairly small, and i have no idea why it even hits anyone but it always seems to catch someone whenever i get caught by it my brain just kinda plays the windows restart noise because the missile speed is pretty slow and elise herself gives such a long animation windup as well its basically giving red lights and sirens a second before she throws it
