My opinion is that many players including myself do not want to waste tokens, greens and time managing a second team. Even if the rewards are substantial enough to offset the investment, many of us like TE because it does not take up much time.

If we had to manage a second team, I rather it be our youth team. At least all the investment eventually benefits our main team.

From all that I read, the only plus points of that were the amount of greens you could get and the club items you could purchase for trading.
