Why I have to be in a CL with only 2 teams of my level?

Why if I go to the SL then I have to be the only team of my level (all L32 but me)?

Why I have to stay 61 editions of cup facing rivals from +1 to +5 levels?

Is not more easy divide the levels in grades of 3? so 1 of each 3 seasons every manager will be in the favourites group?

Tired man, to see how just starting the season I have to face 63 teams that start with a +20% or more advantadge for the face.
