Flex pick?

imo the flex spot should be reserved for mid or adc only

I'd personally recommend fox. He should score more than Meteos unless SK flops hard again this week.

Edit: And don't worry about saving ur flex for only adcs and mids. I've used caboshard and yellowstar, and they've outscored the mids and adcs on my bench.

Generally, you should start Mids or ADCs in flex. They tend to outscore other positions regardless of win or loss (since they have high CS plus usually get the kills focused on them). While it is a good week for C9 with WFX/Coast, C9 also just doesn't get that many kills, so I think Fox is the better choice.
