You realize how idiotic this is when youre fighting a guy wearing heavy armor and all of sudden he does a SuperSonic jump in the air, swing his flamberge and bypass your block because he is above you, right?
Lowering jump height sounds fine too. The point is that we pretty much all agree that removing random jumping and swinging monkeys from regular fights is needed.
Did you realize how idiotic it is to continue looking down while your opponent is in the air? I've yet to miss a block due to vertical location of my enemy. It's more so due to my inability to block in the right direction.
Also, I'm impressed how pretty much all of agree to that thing that most people I've seen don't agree to.
Though I would agree that it's physically difficult to do a horizontal swing with a heavy weapon while in the air. Generating the moment from a dead hault is going to require some spin your body won't be able to produce so easily midair. However, downward swings and thrusts are still quite simply done even in mid jump.
