the key word here is extra. as in not necessary to enjoy the game but can give it replay value. vc is not a bad idea itself but the way it is currently implemented is. you should not have to play a certain amount of any mode to unlock basic features like changing rotations whether its a single game or not. you should not have your rating (for lack of a better word) go down because you do not have enough vc to buy a new weight room. thats the game saying you have three choices: 1) your rating will go down 2) you can stop playing this mode and farm vc from another mode until you have enough vc to buy this weight room or 3) you can shell out some real life cash and buy enough vc for the weight room.
