Polling doesn't seem nearly as bad as it was when the game launched. I've still noticed issues here and there though. I've noticed even if you put G5 teams into better conferences and they win, they are still lower in polls than they should be.
Some teams also seem to be favored in the game engine more than others. This exact situation I've replicated twice now: SMU and Liberty are both in CUSA, both go undefeated in the regular season, and go head to head in the CUSA title game. Liberty won the game each time, yet SMU remained ahead in the CFP rankings. The first time, this put SMU in the playoffs and left Liberty on the outside. This time, neither qualified for the playoffs but SMU was still ahead.
We seem to have come a long way from 4 loss teams being ranked #1 and I'm thankful for that as this is peanuts compared to something like that. But still would like to see things like these addressed.
Ideally they would add an option to let us customize the CFP rankings with an option for online leagues where that has to be enabled when the league is created and it can't be changed. But I don't see EA ever doing that unfortunately.
