Understated chances of ranking up players with the start of TOTY
Before TOTY I always used 4 Mascherano to upgrade players to red ranks, because it was 80% for success. And it worked almost all the time (I think even more, than even 80%) But with the start of TOT...
Nothing has changed - 80% chance is still 80% chance - in theory out of every 100 claims your will get 80 successful and 20 unsuccessful - so you have just had a bit of run of being unlucky after being lucky for a while
