Last year we started the same, after some months (after the TOTY event i guess), everything was fine. I don't know if the problem is the rewards, or the the people who want to get paid for some services or even fulfill their ego on the lower divisions. As i said the only thing to stop this is to remove relegations and keep them on the highest divisions plus to upgrade even more the rewards on rivals WL etc, i know it's not cool for everybody but if they want the casuals to come back and maybe play their game, those are the two best options right now.
