While bumming around on my Warshade, I thought of something that might *simulate* Knock-Toward - if you could spawn a "knockback" on the other side (from you) of whatever you hit. No idea how that would work in terms of programming, and it's super kludgey, though.
As far as the toggle supression thing, even if the toggles still consume END, this is more about stance-dancing, isn't it? The inherent annoyance of having to re-engage toggles when you pop out of humanform for a moment or two and then pop back. A couple seconds of END drain isn't that big a deal.
