The only reason the governing bodies are meddling is because of the greed of the clubs. They had to reform to stave off the threat of a super league. The Champions League iOS nothing to do with FIFA either.
But back to the original question, this league format has been so much better with any more games actually ,meaning something and some of the so called lesser teams having a big impact on the outcomes. I doubt Celtic would have gone through if not had been the previous format. Under the old format the groups had little meaning after a couple of games.
