Bolded the important part for you.
One of the greatest disadvantages to the Warband combat system is the predictable nature of attacks. It is a fact that there would be no duel if no one initiated with an opening attack. How should one approach this then? From my time dueling with edward, he is often content to parry the initial attacks before counter attacking. For the one doing the attacking however, he must make a decision on how to attack, and more often than not it is advantageous to keep as much information unknown to your opponent as opponent as possible.
I agree that deep feinting from across the map is a meaningless maneuver, but you also failed to pay attention to my definition of deep and shallow feints outlined at the beginning of the article. A shallow feint is any feint pattern with three or less feints in the series, ie. a single, double, or triple feint. A deep feint being any feint series with four or more stages. During an actual engagement, you can meaningfully analyze a deep feint series ie. "Rf - Of - Rf - Lf - L". This is a perfectly valid series and also serves a purpose during active engagement and is also coincidentally a deep feint. The reason why I do not devote more time to analyzing these long series of feints I thought was obvious, a deep feint during engagement more than one or two times is going to quickly end up with you respawning because your opponent realized they could safely cheat their parry and kill you with little difficulty. Maybe this was not an obvious point. In any case, I devoted more time to analyzing the other situation - you are jockeying for position with your opponent, just out of range of each others weapons, a deep feint here will allow you to transition into a position based attack with a reasonable chance of success. You are not standing back and feint spamming wildly, you are using footwork to position yourself for an attack while concealing the form the attack will take. I hope that clarified things.
