That you should get locked out of trials after a flawless passage or even moving onto a higher "division" of trials after you've got there. It plain and simply just wouldn't work, I don't know or know if anybody knows exact percentages on how many folk go flawless. But the whole concept of trials was designed so not 100% of players could do it, say for example 15% of players go flawless every week, 10% guaranteed runs and 5% that fluctuate in and out of weeks, and then they get locked out. You're now left with 85% of players that haven't been flawless, regardless of where the other 15% go or do. Out of that 85% maybe another 15% will go, and again and again. Until you're left with a small minority that more than likely wouldn't get their flawless because reset came and took trials away from the playlist. It. Just. Wouldn't. Work.
