There's probably deeper insider stuff we don't know yet but apparently he left so he can have a better chance at winning a title, even though LOUD would've most definitely been the best team in Americas and would've won Madrid if he stayed with them (unless the final ends up being a 3-0 stomp in two days). He should've stayed :/
Now he has to deal with SEN, LOUD, and NRG on LEV (maybe even 100T too if they turn up).
