Despite what people say, there are no rules for sword fights. A proper fight (unless is scripted fights) had no rules, it was just one man against another, aiming to maim of kill each other. A proper sword fight is a free for all fight where anything goes.
In the medieval times, you couldn’t say “Sorry that thrust is not in the rules and doesn’t count.” If someone came at you with a weapon, you used anything including bare fists to survive.
You could call this a rant, which is what its like but there will always be those who complain when writers diverge from what others have written before.
