Skeying is the worst thing you can do against 1h stab. Just facehug and move to their right side (you strafe left into them) and if you have good athletics, they'll glance. If there's a bit of distance, just block. I get them to glance all the time. Adjustments are needed, though, which is why I made that other thread.
Spathovaklion was imo useless when it was first released, since it was just a poor man's iberian mace. At first when making this thread, I was going to say to remove knockdown, but I think reducing weight is more fair and you move slightly faster, too, at the cost of susceptibility to getting weapon stunned.
