An averagely good player can get a 6% roi at the $215's, rakeback accounts for about 2%, so they pretty much got a 33% paycut. On top of that they have to play under there sole Party username, instead of being able to use 3 or 4 to add deception. This will cause opponents to get a read on you much quicker cuz they see you more often. Which also cuts in on your roi. If anything, it hurts the big players more.
