need to watch the axe def tho
my opinion is archers arn't needed much unless you have incomings and need something quick...it all depends on your playing style and what works best for you
i myself come from worlds where they mainly arn't used so i have adapted to not using them...others might like them
Two points that were made earlier in this thread:
Building MA doesn't make building go quicker. Yes you use less iron, but you should be able to farm enough to have rax + stable always running.
Time does matter, when you build cheaper and faster, you can mint more coins = more nobles = more villages which means more population available. Though if you don't have the nukes available to clear those villages, then minting more coins is less useful.
Just be flexible.
But it's a waste to leave the stable to do just nothing. It depends on what you do, but sometimes you don't have the luxury of waiting till your barracks fill the whole farm. Pure infantry is a bad idea, always.
It's only a waste if you need that defense before the time it is completed.
If your defense doesn't get used after your fast recruitment, then your fast recruitment was no advantage. And, fact of the matter is, the faster a defense's recruitment, generally, the weaker it is. So, not only does the recruitment speed not benefit you, you lose out on the possible power as well.
That's only the case when you never fight. Normally you will be using defense before the farm is full, even if it's not for yourself, you support tribemates, etcetera.
The defensive power in the end will be greater, but at any other stage while you are still producing troops the faster troop-production is stronger.
Then when your free population is used, you can either replace those troops for archers or swords, or you mint coins.
