Targeting Macros Help

(not sure if this is the absolute right thread)
ok, so i want to be able to select a mob that one of my party is attacking (i.e. as a DPS i would like to be able to select my tanks current target) thought about using macros, but i don't know if there's a way to just select a single role (tank) or what. right now im sort of forcing it by marking the tank then having the macro select the macro'd person, then selecting their targets. it works but it would be easier if i could just select a role, or a specific person (that i wont always know before hand). OR better yet, they already have some button to solve my question here...

In your controller settings, you can change the button mapping so when you press R3 you will assist (target of target).
If you are using keyboard, you can set it on keybinding I believe.

You can use /psort to sort your party list into a regular pattern. It always puts you in slot 1, but then the rest are configurable (like: tanks first, then dps, then healers). If you use either of the patterns that put tanks first, the tank will be in position 2 and you could use:

/psort
/assist <2>

The /psort line will make sure your party list is in the right order for your tank to be position 2, and then the /assist line will cause you to target whoever/whatever the player in position 2 is targeting. This relies on tanks being first in your (configurable) listing of which order you want players sorted into. A bigger issue is that if you're in a full party with two tanks, there's no automated way to control whether it's your main tank or off-tank who will have that slot 2. (The other will be in 3.)

I have a targeting macro I created after much experimentation and it has yet to let me down. Some of the code here seems unnecessary at first glance but what that does is prevent you from targeting enemies that are marked but already dead- in effect, this instantly goes down the list and back up it again, with the part that targets yourself and then last enemy bypassing anything that's been defeated but is still marked.

When nothing is marked, this grabs the nearest enemy. When one or more targets are marked, this grabs the lowest marked undefeated target. So this is very useful whether in a party or solo, and whether enemies are marked or not. It doesn't include a line with an assist command because there are times you want to target something other than what a tank in your party is targeting; I have assist target mapped to L3 on my controller so I can arrow down to a party member and click L3 to select their target- sometimes that's a tank, sometimes another DPS.

Macro:
/targetenemy
/target <attack>
/target <attack5>
/target <attack4>
/target <attack3>
/target <attack2>
/target <attack1>
/target <me>
/targetlasttarget
/facetarget
