As a Control Player I use 2 sets for it (and all my other classes so far)

Set 1 Left side has the main GCD actions and offensive buff CDs
Set 1 Right side has the mudras, kassatsu and defensive CDs.
Set 3 Left side has the secondary GCD actions and other support CDs.
Set 3 Right side has all utility CDs like Sukuchi, AoEing and Goad.

Set 2 and 4 are meant for macroed quick setup stuff like chocobo stances or level synch (since I FATE a lot) and insta set me back to Set 3.

From pressing Left Trigger -> Right Trigger leads me to Set 1 Left side
Holding Right Trigger -> Left Trigger I get to Set 1 Right side.

So most of the time Im holding both triggers in battle and weave between them, having only 8 skills on screen... should take some screenshots.
