Opinion on Ranked Championship

I have made it to Supreme level - and now it is very silly.

I am constantly playing teams at 170%+, 180%+ and even over 190%.
I am at 130% and stand no chance.

What is noticeable though is the 2 things -

1. How many teams are tanking?
There seems to be a lot more than there used to be. Possibly because by tanking you can get your players to over 180% and the tiers.

2. How many players are upping their squads through the tiers.
How expensive are Gems. The owners of Top Eleven must be making a fortune from this. I never knew so many players spent so much real money on the game!
