The thing is, hitting or slashing someone in plate armor with a sword is never really going to do anything, only stabbing in vurnable places will get you anywhere, but that is not fun in the game, nor really doable for the devs, so that is not a good reference. Though how they used swords for hundreds of years is I think, is. Longswords(or any other 2handed sword)-fighting has 24 for different attacks, excluding stabs. There is no way we can implement all those different attacks properly. Those 24 for attacks consist of 8 attacks with the front side of the blade, 8 with the backside and 8 more, but I'm not going to explain those
. we currently only have the simplest ones, with the front side of the blade. with that front side of the blade you have 8 different attacks, like I mentioned, the ones in the OP. all the different attacks have their own pros and cons, that differs from what stance you are in, your opponent is in and what you're good at. It's bullshit to think that the attacks from the bottom are useless, they pack just as hard of a punch if you hit someone right. So if we add any new attack directions, it should be the diagonal ones.
