[1.2.321] Skill Balancing - Edelstein & Leben

What I have always done (relatively old generation) was have jump as alt, have my main attack as shift, and a mob skill on space. This means that my strafe is on shift, Pierce on space, and blizz on the ctrl button. Anyways, slightly off topic.

Anyone have a clue what this new skill "dodge" in 3rd job archers and "Marksmanship(?)" in 4th job MM do, since I want to know if I should start saving 10 points for the latter.
