WotlK messed up hybrid trees during the first tier. You could no longer put a point in another tree unless you filled out one first. Mainly occurred because BM and readiness in the MM tree.
8) If I remember right, isn't WotLK also when they changed talent trees to only let you place a point every other level, or was that Cata? (I remember in Cata they ^&*^*^ you over on hybrid trees, but Cata is another conversation for another time)
