As of now, you are not supposed to gain an advantage by paying for Supporter or Utopia though.
I think its worth repeating what Perpete said. Especially as it didn't seem to sink in the first two times.
If anyone can't see the massive advantage a team would have where they are operating a second team with the sole objective of improving the first, then no amount of discussion is going to show it.
Even if I only point out that you could train 6 players for one team, while others can only train 3 then that should be enough to show that this whole idea is a non starter.
