PON-PON-POC or POC-POC if you do not have HCA.
I agree with this.
as the team with HCA, if you know that the only way the other team will win G3, is with a PON-PON-POC combo, then you could also PON-G1
If u are good enough to win G1 with a PON and have HCA, then that throws ur opponents strategy out the window.
But obviously you would only want to PON G1 if you definately knew you could win with HCA, even against a POCT from the opposition.
