I suspect you don't read my whole posts, because i write everywhere that upgrading vision is useless. I want to notice that i have some patient to read whole your massive posts.
I can't understand why don't you play e.g. pt 75 x1x1, or even more, like 90-120? With this settings you will have a lot of leather, and maybe so much horses that they will higher in amount than even iron sets (armor+shield+sword), so you will equip even scouts, becides other leather units. Then your late game will appear more often. No need to fix iron, no need in special ironless maps, just higher pt. Ok, maybe you need map with a lot of space both for building and fighting, but not ironless or with low amount of iron.
8/9 units of barracks are balanced, because they can release their value in fight for their cost, and they can do it in the 1st hour of a game. And only scout can't. Horses are expencive, but battle parametrs of scout are weak for that cost, abcolutely can't competite with knight.
I'll write here type if units, when existing of one will make you equip another.
(1) Militia is the main unit in the beginning, but even in late he can be used to empty towers, for some sabotages in enemy's town, if they will get there unnoticed.
But only militia is not enough, then here comes iron units, which you can start producing earlier than leather. The best options there is (2) xbows and (3) pikes. Xbows can kill milita easily, pikes can live under xbows long enough, and pikes are more numerous than swords (x1.5 times), so they can swords easily (e.g. 15 pikes are stronger than 10 swords). Ofc if you have some plans with capturing narrow passages, there swords will be better, but mainly pikes.
Militia, xbows and pikes - basic pack of 35pt game.
Time goes on, corn grows, your town needs some food, becides mill and bakery you can place so leather comes to play. Main leather unit - (4) bowman, because of his attack speed (changed statistic, heh). Finally they appear in so huge number, that pikes can't cope with them, and you need more powerful infantry. Welcome, (5) swords.
But corn continues to grow, and you can build stables. Ofc here comes
knight as a universal unit, whick can tank, attack flanks, scout, attack from behind. Player need to counter them, or at least protect your rear. When big part of your iron goes for swords and knights, pikes mainly are too expencive and unefficient to counter knights (but not everytime ofc), and (7) spears are good and cheap counter.
If you make too much bows, they couldn't shoot at once. Because of this, axes (8 ) is very good option, because in 70-80 minute they can be numerous enough, and in fight more effective than spears.
Bows, swords, knights, spears and axes - basic pack of 60 pt game. Xbows can appear there in special tactic with a lot of them, some players like it. Pikes can appear if you know that yor opponent is a fan of horses, e.g. build 2 stables during pt. But they aren't useless, they are main units on 35 at least.
I'll repeat your question: where are the scouts? Scouts can appear only if you build 3 (not even 2) or more stables, or when your iron will end, and this happens later than 150 minutes. Both of this conditions are close to be impossible for 60 pt game, rare for 90, maybe common for 120 pt, but this gamemode is very unpopular because of very high duration of the game (i mean on x1 speed). To be honest, if a have out of iron core, i prefer to change in marker something for iron core to continue producing knigths, instead of making scouts
There're no maps when scouts in GOOD option. Compelled - yes. Good - no.
I hope you'll read my post attentively, but without massive post, just answer: why can't you play with higher pt, where leather is more numerous, therefore powerful and in meta?
