my take: sen should miss shanghai
arguably this seems weird since this is the team that just won the last masters, but this schedule is terribly cramped and shanghai will burn out the team, no doubt about it. I can't imagine being in their shoes coming back after a massive LAN using every single strategy available to not have your igl available until the day of the split's start to then fight teams with a massive target on you. sen will probably squeak through to playoffs and can win the entire thing but imo it's better of for them to simply take the time till split two and get everything straight
