Another important point is that it is easier to aim a thrust at the joints or gaps in armor than to aim a cut at them. Hard to swing a sword edge under the armpit of your enemy to go around his breastplate.

That is pretty major. After all, who cares if you do have far less energy, force, so on and so forth when the only thing in your way is flesh and bone?
