Thanks for all that detail! Mmmm, interesting, but I'm still not sold. That's still Opposed Rolls, whatever they assert. (Part of current BRP that I dislike).
The manoeuvres may well be fun, but introducing decisions about them into the combat sequence will slow down play, I expect, and also spoil the immediacy (all-important to me) of knowing what effect you have had.
Not simple enough for me, I'm afraid. And introducing manoeuvres for parrying as well compounds the problem already mentioned.
But if the book really does look as nice as all that, I might just get it anyway.
PS: It hasn't got a Physical Rune on the cover, has it?
