I'll keep this relatively brief. I love that Aetherial Manipulation now has a 10 second recast, however the problem I personally have with this skill is that in a tight spot it's hard to quickly gauge which player to use this skill on if I need to zip out of an AoE. This results in me generally resorting to just running normally instead of taking a gamble, which is sometimes the case when using this skill as a reflex since you are depending on where the rest of your party is and some might not all be in safe spots.
Now I also play Dragoon and I love Elusive Jump for getting out of a tight spot and even rushing closer into range. I believe Aetherial Manipulation needs this type of freedom that Elusive Jump has. The difference I'd have would be that Aetherial Manipulation allows Black Mages to dash forward in the direction they are facing. Sort of the inverse of Elusive jump, however it would still have all the freedom of that skill.
Thanks for reading! Hope I made this clear, post any thoughts if you have them. ^^
