It seems like your DR weekly rewards are also taken into account when match making for FUT Champs. One week I earned the full 30 points and my FUT Champs record ended at 4/11. The next week I only secured 16 points and went 7/8. This week I earned 30 points again. My record is 2/7 so far.
It's not even close in some of these games. Opponents are sweating harder than me after a 5 mile run AND 1 hour of weight training. All this for poultry rewards. The good stuff is all in the promo packs in the store. The only saving grace is that they have so many different live events going on simultaneously that eventually I will secure something good.
