I really had gripes with isomotion
1. NO SEPERATION or Beating man off dribble ... You hardly get any seperation with even the best ball handlers vs the worst on ball defenders agaisnt cpu opponets mostly and sometimes online
2. Even if i do get seperation.... The computer will catch up(guards) and even slow CENTERS WILL STAY IN FRONT of your point gaurds because isomotion was compensated with sliding which will be in the game in 2k13 as well because i saw it in the new trailer
3. Hopefully this year we can actually get seperation and beat our man off the dribble AND KEEP IT seperation
