After hitting level 50, and going back to PUG and MAR to get my cross-class abilities, I tried out Jet Brook's layout with a few adjustments.

I made macro buttons for hitting Internal Release before Fracture, Blood for Blood before Phlebotomize, Power Surge before Chaos Thrust (to transfer the buff over to the Jump after Chaos Thrust), and Life Surge before Full Thrust. These buffs always appear before these abilities every time they appear in Avyar's dragoon rotation.

The macros are pretty simple and look like this
/macroicon "attack"
/ac "buff" <me>
/ac "attack <t>

Where attack and buff are the names of the abilities, of course. This way, to get the full rotation off, all I have to do is jam the attack buttons for the buffing macros until the buff goes off and the GCD refreshes. I also make sure Leg Sweep is in the top button for the HT>DOT area, since while the Leg Sweep comes at different points in the rotation, it is always around the HT/Fr/Ph combo.

One problem I'm having with the layout though is getting into position for Impulse Drive, since I need to maneuver with the left joystick then switch to hitting the directional pads. I should be able to get it with practice though!
