Stabs' hitboxes activate earlier as compensation for the turn nerf, but nothing was done to overheads to compensate. Stab noobs like me like this change, and I can stab reliably with 1h now. Previous 1h masters of the stab dislike it.
It would make sense for overheads to be faster (and remove lingering hitboxes once the weapon reaches the ground), but it sounds more complicated compared to just returning it to how it was before. Overheads aren't that difficult to land, but missing can be quite punishing and there's always that little chance that you will miss through a sliver of error, often appearing like your overhead ghosts through someone.
I just don't like that teamwounds are much more common because of it, and that can be annoying because you know that it partly wasn't even your teammate's fault, just limiting game mechanics.
