Maybe it's something I missed but the movesets just talk about Feints like they're common knowledge. At least show Feint in the Icon Legend.
Didn't understand too. I only have a supposition feint is changing stance while preparing to strike. Anyway, it would be better to know exactly from the authors.
I think you're looking for "cancel heavy attack", which is mapped to E on the keyboard by default, B on XB1 and circle on PS4 controllers. Starting a heavy attack and then cancelling it is referred to as "feint" pretty often - I forget if it's explicitly taught in the advanced tutorial, or if it's just mentioned in some of the class videos.
There is a explanation:

Cancel heavy attack
You can cancel a heavy attack by quickly tapping B (MOUSE SCROLL WHEEL) after launching it. Use it to Feint heavy attacks and fool your opponent into trying to Parry for instance, then counter with a quick attack or trying to attack from a different direction to past their defense.
