That's my prediction. I think it will die out in a few weeks. The main issue is that its not
rewarding. You risk 15k and if you want anything of value back you gotta win at least 2 matches online. The majority of players are below or above average so if you lose after your 1st or 2nd match you've lost. So much effort and so much at risk for the probability you'll make the final and gain a 7.5k pack.
They should have lowered the entry fee to 7.5 or 10 at best or increased rewards slightly for earlier losses.
