Old cup format it was L2 vs L15 in the preliminary rounds which was a big problem and pointless and needed to be eradicated. Teams off all levels chucked into the cup and basically the strongest sides were seeded to reach the final.
I once suggested a Level Banded format, L1 newbie cup, L2-L5, L6-L9, L10-L13, L14-17, L18-L21, L22-L25, L26-L29 and so on... Making some cups you enter as underdogs and some cups you enter your amongst the favourites.
