Well... if Jarring Strike II outdamages Phalanx II than is there even a reason to have it equipped due to the fact that JSII not only has a +enmity but also stun effect? I haven't played Gladiator since the patch yet because I've been trying to build materia for PGL but it seems like you'd be able to build off that.

I'm still curious about how effective it would be to pop Ambidexterity on top of a maneuver now. I know it has a fairly long cooldown but iirc the duration 30secs just like the new maneuver duration so theoretically it should work really well in a pinch or maybe even as an opener.
