your performance in the Cup is already assessed in another section of the fan survey anyhow.
also my performance in the league is already assessed in another session!
from a gameplay point of view, you're treating teams differently based on an entirely random Cup draw. That's not good.
This could be a better explanation, even if I don't agree entirely..in my opinion, it would be far more exciting to consider also cup maches, and the difference in treatin would be very small..
