I can't believe I forgot to bookmark this thread before :facepalm:
Shneekey, I have to say that I disagree with your analysis on Leaping Dragon stance, the ring of jumping only gives a competence bonus on jump checks (and it is a bit expensive for my tastes); the real use for the stance is to get the ability to treat all jump as having a running start.
That way you get less difficult DCs, and if you use something like sudden leap you will cover more terrain.
I also think it would be extremely useful on a hood build for example and I am sure a jumplomancer might welcome the bonus
Edit: And now I want to make a Dual wielding Halfling Warblade, that abuses the jumping manoeuvres >_< Thanks a lot Shneekey
