If I have misunderstood what you're saying, correct me.
Misunderstood? Heck, you've been making things up.
You argued against points I didn't make -- for example you argue against hard caps ("then a hard cap is unnecessary, and needlessly limiting.") which I never proposed.
You argue "...if "the game [is] balanced such that other options are as viable..."" -- well duh... Who here is suggesting things should be unbalanced so that other options are 'unviable'? Do we really have to specify the obvious?
You make assumptions, then argue against them.
You want to go back to what I did say? Here:
"Two points:
1- Frogboy(? - or someone) mentioned that troops don't just appear out of thin air -- if you want a large army you need a large population.
2- I'd like to see recruits have differing potentials -- anyone could become a 'peasant' troop, many could become 'normal' troops, some could become 'skilled' troops, but few could become 'exceptional' troops. Training would bring out these inherent skill levels, not increase someone from one skill category up into the next -- ie no matter how much I train or what resources I have access to I'll never be a Michael Jordan or Muhammad Ali.
Combining these 2 ideas, I'd like to think that large armies of exceptional troops would not be possible, as they require exceptional people who, being exceptional, are in relatively short supply. No amount of training time, resources, technology, etc. could enable this.
Thus we'd have armies comprised of a lot of average folks (levies/peasants/etc.), a number of skilled troops (swordsmen/crossbowmen/etc.), and a relatively small number of exceptional units (knights/etc.). What type of exceptional units would vary depending upon resources, technologies, etc. (ie -- knights or samuri or ninjas or ???), but their numbers would be limited.
We could decide to not field large numbers of average troops of course, and just go with exceptional troops, but could not decide to field large numbers of exceptional troops by 'training' regulars to become exceptional."

Picking apart suggestions is valuable to find loopholes, bad logic, etc. Making things up that weren't proposed then arguing against that isn't helpful.
