How the frak do you get out of it? I constantly face players that spam block breaks, especially the ******* wardens with their bleeds, and every single time I can't escape it. None of the in game tutorials or move set videos show how to do this.
You are telling me that none of the tutorials in the game show you how to counter a Guard Break? Have you tried playing Advanced Practice yet? It's under "How to Play" on the main menu. It tells you how to counter Guard Break.
