There is alot more stupid about the buckler.
How can a guy, who holds this little shield infront of his belly, block arrows that go either to his head or his feet, without even moving the shield?
It is a very fast and stable shield, but something has to be done about the "forcefield" of this thing.
advantage should be: strong shield, very fast at blocking and swings to follow
disadvantage should be: almost impossible to block arrows, except if the archer aims for the shield or the shielder immediately raises or lowers the shield's position
