+1 Phaedrus, I find the themes helpful, at least conceptually. Although the mechanics for some maneuvers can be lackluster in practice.
Semi-relatedly, is there a good sense somewhere about where maneuvers should stack up power-wise? I feel like there's some idea that a maneuver of X level should correspond to a spell of Y level, but I don't know if I'm just making that up/intuiting it. From some old online WotC article maybe?
