I agree with you and the OP. I haven't played this game for a couple months now. I used to play 2k's basketball games all year long, but I just can't stand the huge randomness of the gameplay and the ineffectiveness of defense on contact layups, floaters, and hands up defense. Playing against others (even friends) online is nowhere near as much fun as it used to be.
2k11 there was a much greater emphasis and reward in the game on taking good shot selections. The game used to reward you so much more for your skill and basketball smarts, now theres far too much randomness in the game, I assume to make the game much easier on the pick-up and play casual consumer in order to increase sales.
The last couple of years both the gameplay and sliders have unfortunetly been dumbed down. The online gameplay sliders were supposed to have been changed to Simulation and yet the gameplay is way more casual then it was even in 2k11 on the Default sliders that were used. Being a long time fan of the series its been really disappointing the way the game has evolved over the past couple of years.
My suggestions to the devs on the Gameplay, Sliders, and Online:
1. Should be more reward for taking smart shots (especially wide open shots) within a players range with perfect releases. Less reward for players forcing contested shots, especially contested contact shots. Defensive contested contact layups and hands-up should have much more of an effect on a shots success.
Probably around 90%+ of shot blocks just go right back to the offense, I'm not sure what the NBA % is on this but it seems far too high in the game on blocked shots. Its simply not rewarding enough on defense when you do get shot blocks since the offense just gets the ball back most all of the time.
Some Offensive Signature Skills should probably be toned down a bit to balance the game more as well.
2. Strengthen (not water down) the sliders. SIM should play like SIM not Casual.
3. Give users more online options like their used to be. For instance why was the ability to use customized options (sliders, etc.) in private team-up removed? Why were lobbies removed? There should be some form of matchmaking system in the game so that we have more options, instead of treating everyone the same.
4. Bring back a great co-op mode. While private team-up is alright, there needs to be something more in-depth in the game for people who like to play with their friends online. The Park (NBA Jams streetball) doesn't cut it. There needs to be a deep, authentic, competitive, and fun online co-op NBA experience.
