Total bull****, because if you are tanking you are losing points on purpose, except for the fact that you are giving points just to some teams you decide and your opponents don't know which ones.
I didn't decide anything. They played against me exactly in the same manner they would play if I wasn't tanking. I played against all active and strong teams equally, no favourites. All who wanted to win the League, had to play against me.
What's the difference for them?
