Well you wanted to see a source of peasants/gunmen killing knights with handguns of that period and here you have it. Handguns did actually get popular before the 16th century with
I quote http://www.myarmoury.com/feature_armies_burg.html (I will dig through JSTOR if you want academic sources but prefer not to)
> The Infantry of the Ordinance were organized in 1,000 man companies, which were possibly tactical units, though in 1476, when Charles divided his army into eight battles, six of these consisted of a center of 500 infantry with cavalry wings. The infantry, as distinct from the mounted archers, were probably supposed to be of equal numbers of pikemen, hand-gunners, and crossbowmen, but in 1472 at least, the pikes were up to strength, but the hand-gunners only a third, and the archers only half, their number. On occasion the pikes and archers were intermingled, by fours, in action, though the pikes were also trained to form up in front, kneeling down, with the archers shooting over them.
By the 1470s handguns were already popular enough to warrant 1/3 of theoretical force composition. They were used to some extent in the English war of the Roses. The popular image that firearms drove armored knights from the battlefield in a mere decade or so are not correct. The truth is that armored Knights and firearms coexisted on the battlefield for almost two centuries (170 years at least), sadly this is almost never portrayed in popular media.
Anyways back to the topic of guns in this game. They already confirmed there won’t be guns in the first act and I am fine with that. Though I would certainly not mind seeing some in the later acts as long as they have an accurate reload time and are condemned in usage by the higher classes.
