Spells: Canni doesn't give full mana

[mdogornone]

VERY often when I canni (using canni II, but this happened during canni I too) I do not receive the full mana when I canni. Most of the time I get 9 mana initially (or about that) and then the rest after 2-3 seconds. However, today I had to relog because I was only getting the 9 initial mana, and no extra mana. 9 mana for 67 hp absolutely ruins a solo shaman......... I don't know what this is but it absolutely needs fixed
