1) BB said it will never happened. As well as a lot of people explained to you why it would be really hard to do it.
I did not see the "Never", although I saw that they are against that.
In any case, it does not mean that I can't think the opposite, and although all the known problem they have with that.
In addition, on that it seems that those who wrote here also support this. Not that it has any importance.
2) Several people in a lot of threads explained to you why old teams would still get advantage from that.
Those where the same (very few) uses who are all ("by chance") old users / play at the DIV-1 or DIV-2.
And in any case, I proved that wrong (or on some of the cases a literally lie).
Starting in a lower league would allow teams to discover the game (unknowingly they are playing against bot, because yes, most of them do not know that) and build their team before facing teams of the next level AND following the proposition they will be placed in several league and not just the harsh one.
They will face the same wall and leave.
It is a fact that we don't see any real growth on any nation - users join, play until they are coming to the wall and leave.
This extra season will not change that.
Anyone who will go to the Nippon league can see what rosters (or Arena size) the "wall" (those teams that stand between them and being able to be promoted) have.
A single season will not change the new users when they get to that division - it still will be a wall that they cannot overcome.
