Played with the new JA a little this morning.

I was able to land an enfeeble (Paralyze II) on a mob (Flame Skimmer in Abyssea - Mis) that was "completely resists the spell" using the new JA.

Right now the JA seems to have no recast timer on the test server, but I can tell you this ability is barely worth 10 minutes, nevermind an hour or more. Even turning around and stacking Paralyze II with Saboteur was unimpressive, especially considering I had to burn two timers to do it.
