I personally just don't care.
I play this game out of enjoyment of the PVP aspect.
It is intense, quick-paced, and most importantly fun.
I don't give two ****s what the champion looks like, I play champions based on their performance and my personal playing style.
Do I mind that the females are obviously, how should I say, "incorrectly preportioned.?"
No, I don't.
But, I don't personally feel it matters at all what video game champions look like, considering that it actually has nothing to do with their ability to be played. (although larger champions can make it more difficult to target smaller champions, such as a chogath at full size standing on top of a teemo.)
Just my two cents.
