Fatigue is not very realistic!?

[Excist]

The way I think of it is that each 'swing' isn't really a swing, but more of a measure of what they accomplished in a set amount of time based on action points and their capabilities.

As such the swinging of the weapon is a minor part of their activity and has less effect on how quickly they tire in a fight compared to factors like how healthy they are (muscle:fat ratio and whether they are elderly), and how heavy their armor is.

For example a big hulking brute might have 1 attack with a big sword, but it takes a lot of swordplay or maneuvering to get that opportunity to swing.

A small lightly armored character wielding the same sword might tire fractionally quicker on the swing, but find it easier to get in close and take a swing.

The only thing that is slightly unrealistic is that a dagger and a huge axe are equally tiring, but the amount of fatigue the actual fatique is over the course of 1 round of swordplay can be rounded down to zero.

Lets turn to our expert on the subject of fatigue in fantasy universes,

Its not wrong that the weapon does the same damage if its the same object.
The actual damage in dominions is weapon damage + stenght
so giants do more damage due to their strenght. I do not see the point there. The same sword awards the same damage because its the same piece.
And why do the bigger units have to get different fatigue? I have issues with other things like a spear doing 3 damage and a sword 5. Why the spear does little if they stick inside people while sword cuts people.
