Cant seem to feint>GB a Gladiator's parry attempt

Title

When ever i do it and the gladiator DOES attempt to parry, my GB doesn't seem to catch them within start up frames.

Feels like that the two new characters were both added with aspects of the PTR, Highlander's being his no GB off parry, Glad's being that his heavy's GB vulnerability being only the first 100ms

Obviously the best solution would to be just parry the heavy they throw out in attempt to parry, since thats what you would do against centurion, however Gladiator's heavies are 700ms, not 600. So not only does this mean that gladiator has a very small GB window for a average timed heavy, but he also has an easier opportunity to feint his own parry.
