I never thought I'd see a weapon less practical than the doublebladed lightsaber, but here we are.
I'm not sure which part of that weapon is dumber. The fact that the energy part of the crossguard increases your chance of cutting your hands off at the wrist by about 1000%; or the fact that, because the non-energy part of the crossguard extends so far off the base, it doesn't actually protect your wrists from enemy attacks at all.
The whole point of the crossguard is to lock the opponent's blade at the 90 degree angle where the hilt and the guard meet. Which, in this case, would result slicing through the guard as though it weren't there.

I believe the Moviebob has summed up arguments about the lightsaber claymore better than anyone else:
"THAT IS A COMPLETELY IMPRACTICAL REDESIGN FOR A SWORD MADE OF LASERS THAT CAN ONLY BE WIELDED BY A SPACE-WIZARD!!!"
The entire concept of a lightsaber is fantastical, adding laser hilts to it is not going to ruin it. I'm more intrigued by how the blade is...weird. It's not like the other sabers where the blade was a solid mass of light. No, this one seems to crackle like electricity. Maybe it's a new design we haven't seen before, or maybe it's a hint to something about the character. At the very least it gives the saber a certain menace to it.
It's not that the crossguard is impractical. It's a liability. It offers no advantage and only makes an already crazy dangerous weapon even harder to use.
With the lightsaber itself, you can at least make the argument that the benefits outweigh the risk of usage.
With the crossguard, the weapon is objectively worse than without it.
