Honestly think this is going to be a close game as both teams have 4 days to prep. I think that PRX has the advantage due to their playstyle, and I believe that Optic will lose this match.

PRX 2- 0 OPTC
PRX 2- 1 OPTC

Now if OpTic can survive their own curse and actually defeat an EMEA team, then I do believe they have a shot of winning this event, as doing so will probably remove a mental block from OpTic and, as a team, they have a high percentage of winning revenge matches.
