they are forcing split on every game to hide their map pool I'm pretty sure but not sure as to which map they're tryna hide, I thought it was haven but now I'm not sure
they wouldnt scrim abyss when its not in rotation, especially because how hard it would be to find scrims, let alone a good quantity and quality of scrims
I definitely think they are playing spilt to hide strats.
However, its a pretty amazing map for them for the next 2 weeks. Its a map that is less likely for teams to be practicing, and Sen are really good on it.
