I got it. My strategy for getting resiliancy: get your opponent to all red damage before letting him start attacking you. This way, he's slower going for covers and you have a bit more time to recover. Once he's got two of your body parts to red damage, start intentionally missing dives. Like, diving when you know the opponent is too far away. After a few tries, with a little luck, he will try to pin you for the brief period you're on the ground from missing the dive. That way, you're barely down when he tries to pin you, and it makes it easier to kick out. Still reuires a ton of mashing, though.
At least this strategy is what worked for me.
And yes, they do need to rework the pin system.
