A val roster needs to follow a line-up and the line up usally looks like this
Duelist
Flex
Smoke
Initiator
Sentinel
This is usally the core line-up for any team so what regions make the best players for each role
Duelist- SA in my opinion make the best Duelists even when they are badly losing they are still able to have huge impact on the team and sparks the rest of the team to come back they have incredible aim and can entry onto any site and are guaranteed to get a pick on the enemy team such as LLL Aspas, KRU KeznitdeuS, LEV kiNgg and many others
Flex- APAC in my opinion create the best Flex players one we can use for a example is PRX Jinggg in my opinion he is one of the best Flex players I have seen ever touch this game apart from SEN SicK but also many other APAC teams such as BOOM and XERXIA even including ORDER have amazing Flex players like BME Famouz, XIA Sushiboys, ORD disk0 and many others and prove that APAC make the best Flex players
Smoke- NA in my opinion create the best Smoke players time and time again they have proven their massive fragging potential and shown how adaptable they are to any situation and their ability to win nearly any gun fights they get into for example OPTC Marved, 100T Bang, XSET AYRIN and many others
Initiator- East Asia in my opinion create the best Initiator players for example DRX Stax, ZETA Crow, NTH JoxJo, EDG nobody and many others have proven themselves many times on the international stage and proven they are the best Initiator players
Sentinel- EMEA in my opinion create the best Sentinel players for example FPX Suygetsu, TL Jamppi, M3C Chronicle and many others i understand Sentinels have fallen out of meta but when they are used there power is always shown and EMEA best shows it with their players
