First of all, I think it's important to remember that it wasn't really all that long ago that people were widely discouraging the use of archers because, supposedly, they were strictly inferior to infantry, and would never be as efficient in practice.
And in most cases, they were actually right, because of a bug in the combat code that stood unnoticed for nearly a decade, causing archer damage to be inadvertently divided by 3.
So if archers are, given some careful experimentation and favorable conditions, now proving strictly superior to infantry in practice...I think what that means is that we've finally managed to undo the damage to their reputations that years and years of actual underperforming will do. And all it took was buffing their damage several more times after fixing the aforementioned bug.
I will make a note to look into nerfing archer damage a bit in the near future.
