I actually find no fun in fighting the same opponents level all the time, I do prefer random opponents.

The cup is not about the same level or same quality, it never was, the CUP have to be unfair but the trick with the CUP is to make you to be at the lowest but also at the highest quality from time to time.

Take the CUP system from any country you want, you won't found a fair competition because CUP is not about being fair, CUP is about making the impossible possible with only one try.
