I 'do not agree' with that, my ugliness or stupidity is not a factor though, as this is a game. Movements are analogies, not exact representations. When you start adding limits because of 'reality' to this flawed model you are detracting from the flow of the game.
Or adding to it, depending on your subjective preferences. Mount and Blade wouldn't have been created if it wasn't for some turkish dude's hunkering for 'reality'. I'll bet you a +3 katana that Armagan created directional combat as a vehicle for realism and not the other way around. But you probably already have all the katanas you'll ever need.
So why do you really want this? You want everybody to stand toe to toe until a block failure or to enjoy, as you put it, a ping spam competition? Know what is daft? Holding a weapon in the ready position as long as you want then swinging it as well as if you had wound up and swung immediately. There is an endless list of what is daft in the game, but you advocate eliminating a playstyle because you do not like it.
I think players would naturally compensate by increasing athletics and weapon master, playing cavalry, playing a ranged class, and/or favoring faster weapons. Swinging 2h and polearms around like light-sabers is Hollywood cool and all, but it detracts from what I see as the flow of the game.
