Usually I have some mixed feelings about this sort of thing, but holy s*** this one isn't even close.
Battlecast all the way. This poll (more or less this topic) isn't even needed. --- He asked if it was possible for a male human to have a sex with a female horse. He even drew a diagram; I think a stepladder was involved.
Personally, I think Battlecast Cho is one of the best skins in the game. He just has so many new particle effects.
Anivia's particle effects changes are cool, but not always noticeable. --- On the field of honor, the gods bearing witness to my glory, I will pull your entrails through your eyes and use them as reins to ride your soul to hades below!
If possible,get both like me. If not,then cho. Cho has more viable roles than anivia so you'll get more use out of the skin --- Trollfaqs,where haters hate and basement dwellers trash others to feel better about themselves.
Battlecast Cho screams try hard. It's like what happens when you put more sprinkles than actual ice cream. It's just over decorated and doesn't really leave a good taste. --- Your mission, should you choose to accept it, is to find the monkey. http://www.youtube.com/watch?v=GJiIkRwS8Wc
