Thought I'd start this thread to see if others felt the same way.
A) Picks
2K18 - Picks set for you from your teammates are completely useless, they don't even slow your defender down. On the other side, the cpu's picks are like brick walls. I've tried for 5 seconds to run through a pick to no avail.
2K17 had the perfect balance of picks, slowing down defenders well depending on who was setting the pick.
B) Speed
2K18 -My 99 speed guy is comically quick. He is insanely fast. However, I've noticed that as I leveled up in speed, it seemed like the cpu defenders did as well and that the entire game just ran at a faster game speed, not just my guy. The speed I sometimes run into defenders should, in real physics, crack bones.
2K17 - perfect balance
C) Mypark
2K18 - hate it. Hate everything about it. From the pointless neighborhood (waiting to use the Gatorade reaction time machine???) to the atrocious top down view in Mypark to the horrendous load times. I've visited MyCourt once (what the heck is the point???). Stupid green dot symbolizes where I am in Mypark and I cannot find my squadmates NOR walk around with the top down view.
2K17 - simplicity works. Love how I was able to get a top down view and see my guy and my squad mates and all meet up at the same court.
D) Matchmaking
2K18 - I don't know if this is a console thing but in order to squad up with a friend, my game needs to quit to main menu, reload mycareer so that we're both in the same Neighborhood. And even then, it would sometimes not find my friends.
2K17 - simple matchmaking and pro am
E) Gameplay
2K18 - court spacing is terrible. Teammates do not give you space to move. My 99 speed PG would beat his guy only to run into a secondary defender. However, my dumbass teammate would just stand there and not go to an open spot to make himself ready for a pass and score. Playcalling did not help much either. Footplanting is also nonexistent. Many instances of my guy running in place. Skating.
2K17 - seemed to have smarter AI on fast breaks and court spacing
Honestly, I cannot think of one thing that 2K18 is better than 2K17 at.
