The "Myth" of the "Dacian Falx" as a super weapon

[nina]

It is the falx that is an abberation. If it was such a wonderful design then we would see just as many variants throughout the world as the scimitar.

You said it yourself: there are similar looking weapons, as the scimitar, but only in Asia. This can only mean one thing - those weapons are suitable for a very particular fighting style. And for the europeans was a strange looking weapon.
So we can say the same about the falx - it was used in a special way, very different from the Roman one.
And to adopt a new weapon like this, would mean for the Romans to change a very effective fighting style. The Romans only adopt weapon type that could fit in their fighting techniques, nothing else.
I don't believe I've used the word "wonderful", you stubborn one.
