As probably everyone knows, Gplay recently upset Envyus in a B01, in D2, which Envyus don't like very much.
The fact it was a close game (16-14), concludes it for me. Gplay, got lucky, and Envy were in a slump.
Envyus are in a bit of a slump, and are not performing well, but I do not see them losing 2 maps to Gplay.
Gplay may get lucky and win 1 map,and if so, it will be very close.
So in conclusion, I believe Envyus will win, whether it be in 2 maps, or in 3, I think that the final score will be 2-0 Envy.
