SEA teams didn't do well the first two Masters last year so teams didn't study nor pay much attention to SEA teams.
The proof is many top teams refused to scrim with SEA teams at Champs first but they found out they were quite decent after some scrim blocks
Now that teams know SEA teams are good enough to beat other regions, they will be studied more than ever
This masters will be the real test for them
In this case, Zeta can be a big underdog since nobody really studies them hard
