Wynn have stopped using the discard tray?
That's extremely bad news. I mean, 16.6% pen is simply too unreliable to card count against, so I don't see how there can be any substantial game protection benefits derived from doing this. Possibly its to speed up the game?
Regardless, the slight increase in variance made their game more fun.
I'd still play it. The house edge is 0.08% if they put the cards back into the machine each round. But I won't hide my disappointment.
