I have two macros:

*BUFFS*
These are "Blood for Blood", "Internal Release", and "Keen Flurry". There are no /wait commands, so I hit the macro as needed.

*TRICK ATTACK*
While "Trick Attack" is not macro'd, the queue for it is. So, when I'm preparing "Trick Attack", only the start of it is macro'd to let DPS know it's coming. I have the other two Ninjutsu on each of their own button. On Playstation, I hold L2 then hold R2 as my main Ninjutsu bar, with Ten, Chi, Jin being SQUARE, TRIANGLE, CIRCLE, respectively while holding R2 then hold L2 is specifically used for Trick Attack's setup, in which case SQUARE is the ready macro. Here's how it goes:

Hold R2 then L2.

Pressing SQUARE has:
/em is setting up {Trick Attack}.
This allows DPS time to buff up their power. Then I just hit TRIANGLE, then Circle. I hit X (Ninjutsu) when I'm behind mob.

You need to see it in action. It's so simple.
