Yeah ok, if you think that archers alone should shred anything of course you can’t push, but you know, it’s really common to add some siege to your archers to destroy the enemy buildings, and BBC or hussars to snipe enemy onagers.
The archers kills the melee units that try to kill the siege, and the siege kill buildings and enemy siege? Otherwise why archers+SR or archers+BBC are some of the most common and powerful combos, with the addition of either halbs or hussars?
Well, that pros should be considered the only people who play the game is correct, but they do know the game better.
As for the second question, it’s because manganels are cheap and can easily fend off, or even discourage the enemy push. The value that you get by even a good manganels shot can easily repay the cost for the manganel itself. And even if the enemy can out-micro you, he probably dedicated so much attention to the micro that his eco will be worse than yours, and you can always have another manganel pop up.
It’s the same thing with monks, even a knight converted more than pay for the cost of the monk, and just the threat of it make you enemy more careful.
Yeah well, than there is no point on even make HC if you don’t micro or use a meatshield onestly, like half of the units in the game…
Serjeants are simply too expensive to be chosen instead of champs, and too slow to make effective use of that armor, since range units can micro them down, and most melee units can avoid engaging until they have an advantage (hills, more numbers…).
But champs will always be easier to mass.
I think that either one or the other it may be enough.
Either you reduce the cost (not through first crusade) so your feudal pushes with serjeants and donjons are more efficient (maybe you need to reduce the cost of the donjons too though), or you increase the speed and base attack/attack bonus (vs buildings), so they are more effective.
In the end, look at the only civs that consistently use infantry in the feudal age. Those are either the celts or goths, so we should take example from them.
