So let's make some calculations.

With my main team I invested about 500 tokens and greens, played I lot of game and reach 120% quality. Nice. With my test team (almost abandoned) i didn't invest anything, played about 10 matches just to test some tactics and reach 90% quality without any effort or tension. Now it is time for math. In my first team I meet 110% opponents, they are 9% weaker than me. In second team I meet 80% opponents, they are 11% weaker. So in others words, I pay for meet stronger opponents lol
