It makes it pretty pricey considering it's already 40 pts and
TL LC are 30. 15 is probably better, pay for the lost wound at least. Considering it's now a 55 point (two-handed) weapon it's not unreasonable that you get your basic attacks in close combat.
The old rule was that when you caused a wound you took a leadership test, and if you failed it you lost a wound. Or something. Whatever it was, it was much better
IMO.
Losing your attacks isn't the worst thing in the world considering you're only getting your base attacks + 1 anyway.
It would certainly make the Khorne weapon much more viable. Almost _too_ viable
