The lowering of quality doesnt seem to help for associations. I have to admit that i have tried it and i still drew strong opponents. There was a thread months ago saying it was the average quality fielded during the week, that doesnt seem true or is not working as well.

I have been getting random draws and results. If the engine wants you to lose, you will.
But at least now most associations can stay on in platinum for a few seasons before the engine relegates you. It used to be much worse.
