This is just the tip of the iceberg in terms of what kinds of hacks can be done in For Honor. The only reason there are not more is because how severely unpopular the game is.
If I dedicated enough time I would make a script that does not work on pixel detection, but by sniffing incoming data package content to make something that always parries/deflects/counter-guardbreaks regardless of feints.
And since there are no servers to authenticate my data packages there would be 0 consequences.
Popularity of For Honor is a double edged sword; if it stays unpopular as it is, then we wont find any matches to play; but if it gets back its population and popularity than it will be a silly hackfest.
