Fair?

Ive recently been playing the new challenge but this goes for any challenge. In the challenge section it says that anyone lvl 8 and over can play. But when say a lvl 10 fights a lvl 12 who is 3 leagues higher than him or her doesnt make it fair. I know the crown challenge is to show who the best players are but at least go from weakest to strongest and that will show a players true ability and allows players to collect rewards and know there own talent.
