i totaly disagree, holding down "A" for 2 or so steps to gather composure for a power move is a very real gamplay element. ive used this analogy before but: take J. Bettis for example his shoulder charge should be much more effective if he has a few steps free of contact to gather himself for it. as opposed to lowering his shoulder in a split second response while running. If he knows he is going to meet a LB and has those free steps to load up LOOK OUT!! this is the first game to seperate bracing for contact and sprinting.
I think its our preception of "POWREING UP" making some feel its unrealistic. Its the same with most moves when yo have time to anticipate and prepare for it , its gonna be more intense. no one can pull off there most powerfull of efective move at a moments notice. In real life when i get a slam Dunk, its much more intense and powerfull if i have my 2 free steps with no contact, and i know im about to dunk.
If you dont like it thats fine but until there are better alternatives for this gameplay element they would be crazy to remove it. the 2K diehards would be ticked. simply pressing 2 buttons shouldnt instantly give me my most powerfull shoulder charge.
