Guess I'll jump on the bandwagon for a moment and say that I'm starting to wonder about this myself.
I just finished two matches with an enemy who was parrying and grappling me for actions I finished taking over half a second before.
I'd be halfway through a Triangle attack (Zeus Hammer and Minotaur Hammer), and he would suddenly grapple or parry me as if I was still dodging or using Square. His I-Frames would kick in during my combos, and I'd also be hit by his triangle even if on my screen I'd hit him first (usually with a light attack.)
I understand that there has to be a decision making process for the game when two console viewpoints collide, but it's still irritating that I get sent flying from an attack I was countering.
EDIT: I just want to be fair and say that I get up really early, and that this time of the day isn't prime, and I was probably being placed with international players.
