Yes, you are right looking at it from the second league's point of view. I was looking at it from the position of the top league. But still in comparison to the status quo there are four chances to come up rather than one. Still don't like it but can see the arguments for and against.
My biggest issue is that in the top league one or two teams will get detatched even in the first 22 games, these teams just down tools until the 'new split'. Also, what is the timing of the split with respect to the January window? i am sure your transfer activity will be linked to what league you will be in.
