TL vs C9: Game 5. Wtf was TL doing?
Well let's start at game 3. TL was going for the infamous jugger'maw build but they prioritized obtaining Kog'Maw over Corki in draft pick when Corki essentially plays a larger role in the jugger'maw build than Kog'maw himself. Corki would have been a safe pick for ADC if C9 stole Kog'Maw afterwards, which would be very unlikely considering their team comp.
Fast forward to Game 5. The winner goes on to the Spring NA LCS finals. And what does TL do? They don't ban Hecarim and they go with Lulu mid. LULU MID.
