Well, what is sure is that we reached the limit of the current league structure, especially with the tanking.
There isn't only the gap between both confs, there are also the schedules.
How many of us haven't already had a schedule where, every week, we played against the team that will have played just before against a team who doesn't compete ? This a total season changer.
What's more, schedules often repeat themselves between seasons (having 3 matches outside on a row, etc).
So anything that might break those things and create more randomness would be welcome
