Not to mention that increasing an incredibly useful enhancement, that is more or less completely balanced to cost 3 more AP for the same effect (even if you need to put less points in vanguard) would not be a very welcome change.
Now: 1/1/1 AP for 5/10/15% movespeed I would be completely happy with.
