At the speed that you are developing I firmly believe MBBA would be a very competitive league (not that it is not right now).
not to seem negative, but my understanding is that training is still suboptimal, not being widely monorole, neither in MBBA nor in II/III series. The symptoms is the level of 21 yrs old players. May be wrong, as being a symptom, but likely.
If II/III push hard on training, MBBA will become far more competitive, otherwise promoted teams would defeat incumbent ones

at this moment, first week matches evaluation are similar to low-II/high III in Italy, just to give you a reference point, where incomes are far lower and is more difficult to manage growth.
This is just to stimulate all of you: look at most compettiive countries, aim to their levels. Challenges accelerate growth.
And I love reading about people who aim high as you.
