Dear Riot: Make IEM play on the Live patch, not 5.21

We're done with season 5. SKT already won. What's the point of another tourney on 5.21 when everyone else, including PGL, are playing on the preseason patch? We've still got over a month until IEM, that's more than enough time to give all the teams time to learn the PBE patches. IEM is going to look nothing like the game everyone else will have been playing for over a month; what's even the point? We already know how strong GP and Morde were; Let us see the pros playing all the new adcs.
