I aim to eliminate the human error to help me perform.

There is no need for macro. Have everyone but the main-tank stand in the same spot at where flank and rear happens so you only need to strafe left and right to do your combo. Stand slightly in front of them, between the group and the main tank so everytime there's a homing missile, you'll get it automatically and move when you see the tethered line. They even made it more visible now. For brainjack, I think it's every 30 seconds but you can always focus target the boss and look what he's casting.
