OK I see about the men part, but I don't remember any Nightsisters using TK... and I mean if they chant for most things apart from the basic abilities does anyone really care or notice?
except any time a nightsister in the show did TK they did it with out words thus it was altered. The Men had their own camp thus it was altered. They were not all the same species thus the back story has been removed entirely. I just said all this.
EDIT: Ultimately I suppose its a matter of preference, and whether you prefer the changes or not.
