From what I count there are about 10~12 first tier teams in our community (not sure how many will sign up).
I learnt from World Cup Ro16 and BoA qualification, that the difference between 1st & 2nd tier is quite big.
And also, a 4+4 format is simpler and faster.
It's a pity to lost some 1st tier teams in Main League, but they can still fight for some prize money/award in Gold League, where I think at least top 4 will still be very competitive.
I'm thinking about distribute more prize to Gold League when the prize pool goes higher too.
