Optic: Marved
I say Marved here and not Yay because you can ALWAYS depend on yay to frag. He'll drop 20 every map minimum, what's really going to need to show up is the support players, and the best among those is Marved. If Marved can cleanly anchor sites like he usually does, It's going to be a long day for Optic as they constantly need to retake at the man disadvantage.
Loud: Aspas
Aspas gets the responsibility of OP dueling with Yay, easily one of the hardest things to do as a pro player. Aspas needs to be at the top of his game and make sure he doesn't get completely differ by yay so he can wreak havoc and allow the rest of his team to be at ease knowing they don't have to be in fear of el diablo at every turn.
