I know, I'm late to the party here. But, I do agree. I think sliders definitely affect this "rubber band" feel. I have had quite a few games where I won with no problem.
I wish EA would chime in and give us more detail as to what the sliders affect and how they "domino" to other sliders. At least give us some sort of idea so we can adjust accordingly. When you read the description of some sliders, you get confused if it should be placed higher or lower. The wording of the sliders the can be confusing. However, each year someone asks EA for this information, EA goes silent.
Now, I'm not ruling out some sort of "rubber band AI". Heck, someone got into the code of the FIFA game on PC and found code that said something along the lines if the player is up by a goal or two, slow their speed down or something along those lines.
I understand EA wants the game to feel like "hockey", but hockey is an organic sport. Every game shouldn't feel the same. Every game I'm leading by 1-2 goals, I shouldn't be thinking the CPU is going to score with a minute left to make the game exciting. And this does happen more than not. Not every team in the real world, scores goals by pulling a goalie or with a minute left.
It happens, but not as much as it does in this game. EA should not be forcing this game to be fun. That is up to us as players and how we play the game.
