An american playing 10 games of Halo a day is getting the same exprience and practice as an Australian playing 10 matches too. But yea I know why we get beaten by Americans when we verse them from our country over the internet is due to lag and server placement (surprise most game's servers are in america), and why Americans are like lol what is **** when an Australian hosts a match instead.
This is a fantastic example, and I'm very glad you brought it up, because you have highlighted just where your reasoning falls short.
At higher levels of play, an Australian does NOT get the same experience playing ten games of Halo that an American does, for the exact reason I outlined earlier. In the US, teams like Instinct, Status Quo, Warriors, Dynasty, etc, etc, are scrimming each other constantly. Because there is a much larger competitive community, there is a much greater amount of high level competition going on. More players rise to the top, and more players get extensive experience playing on LAN, and are able to develop their skill set to a much greater degree (this is on top of a larger playerbase lending itself to higher peaks in terms of individual ability).
By your theory, Team Immunity should place near the top of MLG Halo tournaments, but instead they get eliminated by teams like Reality Check (LOL). They did manage 9th in the recent Halo 4 event, which is definitely impressive, but then again they have Ogre 1, so they're only 3/4 Australian strictly speaking.
Also lol at assuming the US or EU are the best at starcraft, is that the koreans I hear calling?
Lol at your sad attempts to errect a strawman. That's not what I said, and you know it.
