@Kamelpov Using the Total War games as a demonstration of your baseline is both a very illuminating and very bad choice.
See, the issue here is that you keep making an unspoken decision to use what I call Opportunists as your sole point of comparison. Just like the Total War devs, you're ignoring the notable chunk of Professionals that is always present. Opportunist Mercenaries contributed to the fall of Byzantium because the ruling class at the time was so sunk in backstabbing political nonsense that they were incapable of telling the difference between the two, or dealing with them in good faith. Too many Opportunist mercenaries hired, too many broken deals, too many weaknesses brought out in the open.
Also, if anybody is using this manga as a point to claim that conscripts are better than mercenaries, I kind of need to pointedly remind you that the MC is literally (though inadvertently) using magic to mentally influence his subordinates (Blessing of the King), not to mention his status as "Son of the Griffon, Lord of the Hidden Village". Trying to use blatantly fictional, in-their-own-setting uncommon factors to claim that what we see here is somehow a standard baseline is completely false.
A more realistic portrayal of mercenaries is the recent Issak manga, or Hawkwood. The big bearded fellow in Issak (you'll know him when you see him) is a good example of a Professional mercenary. Hawkwood himself skirts the line but manages to fall on the side of the Professionals, while the black-haired fellow who tries to backstab him is an Opportunist.
@RhoninFire Mostly tagging you cause I want more discussion. And Machiavelli doesn't make the same claims that anyone on this thread (or indeed most people in general) make. Machiavelli's problem with mercenaries was that, if not closely managed, some mercenaries had a tendency to not commit to winning the fight and thus drawing out the conflict for more money. In terms of straight performance or matters of personnel, I'm fairly certain Machiavelli never claimed they were categorically inferior to state troops.
