I don't nudge, never have, never really will. Just don't see the point. While everyone says its part of the game, I think it was with EM's etc. With these games its the mostly about the shots and the skill. Passing the ball, holding, etc. So i've never done it since it doesn't feel natural to me.
Do I care that others do? Nah. However I've seen a few people violently shake games, I wish you could have the game hit them back...
