Anivia Q

Lately I've noticed that every so often Anivia's Q will disappear half way on the way to a target and it won't appear again unless it hits the target. I love playing her but the amount of mana she needs early game and how incredibly slow she is can get frustrating at times. I think if Riot would up the movement speed and amount of starting mana and mana regen and traded it of a slightly longer cooldown on her ult or maybe less damage on her stun, it would keep a good balance yet still satisfy players. Just my thoughts
