Nothing they can do about it. Most of the work people are doing are account recoveries. If they made it so a user could only go flawless once per week it wouldn't touch people that are playing on the client's account. I mean, flawless gear is purely cosmetic. It lights up. That's the difference between it and the other trials gear. You can get all the weapons by winning a couple of matches out of 7.

When money means nothing, people spend it on nothing.
