Unfortunately the most successful bases and theirs not many most people use the same ones.
Base 11, Base 49, LaMarcus Aldridge & Set Shot 13 & Base 24 for locks and bigs.
It makes the game pretty boring seeing everyone with the same shot.
You have to get the right base as releases dont really matter.
In Park depending on the latency for that time you may have to adjust the timing of your jumpshot to release it earlier or later.
Also most people have different jumpsuits for different modes online because the latency varies between each mode.
