We've all been there, you just got finished playing one FPS, switch to another, and subsequently spend the next two weeks getting stupidly killed while trying to perform some trivial action like crouching or melee attacking and getting another result. I've recently started playing Battlefield 3 after having spent over a year on Black Ops and just when I was getting used to crouching by clicking my right stick, I had a friend visit me and pop in Black Ops; needless to say he fragged me like 15 times when I was trying to crouch and just ended up knifing the air in front of me repeatedly. These are first world problems, I know; but come on, if developers refuse to allow us to remap controller schemes, then they should at least come to some kind of consensus and standardize them so we don't have to go through this stupid learning curve every time we move to a new game.
