That's the thing, people need to play a ton over multiple days before talking about changes. A lot of people (myself included) are prone to instant reactions after one or two matches, and then we frame everything after that based on those initial impressions. I know I've sworn I've noticed changes in games from day to day, with or without a patch.
Some people will swear that a game will change on its own as it learns how you play, or they'll see similar dynamic difficulty/scripting, etc. I just think people will convince themselves of things and there's no way to dissuade them. But I digress.
