But to try to detail more of my thought process. In the Before Times, larger formations had the benefit of an increased concentration of attacks, and defenses. Defenses totals for the entire force also didn't really matter, only the level of defenses that each particular formation had. Yes, having multiple formations did lower the chances of the enemies stacking more than one of their formations against you, but someone was always going to be getting targeted and having more, smaller formations that had less defenses meant there was a greater chance of those attacks being undefended. Reman's video that shows 1x40w v 2x20w, and the 40 wins is due specifically to this phenomenon. The same amount of attacks are being thrown at either side, but the 40 has more defenses in the formation that is getting hit, to reduce the damage those attacks deal.
That is no longer true. Having more formations will generally now lower the amount of attacks that each formation will suffer, so they won't suffer quite as much amplified damage as they did before due to lacking in defense. Another graph!

This graph is largely the same as before, but it adds a green line for the way that damage would have been spread out in the Before Times. We can see that with the yellow line, it more or less halves the total damage it suffers at 92 defenses, while the green one doesn't cross 200 hits until 356 defenses. You would have needed around 4x as much defenses in the Before Times to have the same level of 'damage reduction'. I suppose what I'm trying to get at here is that stat concentrations don't matter as much as they did before.
