Well I do not tank, it's only because I am progressive getting put into higher and higher CUP level draws.
Season 4 at level 7
Season 5 at level 8
Season 6 at level 10
If I could manager to remain at a Level 10 for season 7, I believe I have a chance to make it to the semis' or better. The remaining games is sure-win for me, and the League title should be safe in hand. So I can fore-go improving my players for now and train and save my skill points.
