I attempted to get this working a couple months ago, but after many tries couldn't find a workable solution. As I was just getting my teams going I went back to a focus based set-up and proceeded to level up a few RAF groups. Fast forward to today, I find that I would really like to free up focus, so I've taken a second look at the FTL set-up. My understanding is a bit better now, so I'm hoping I can more clearly articulate the problem I'm encountering than I did back in November.

The set-up works well for abilities that are tied to one key, however, I'm having trouble when using shift+key. Take for example Shift+4. I have the following hotstrings set-up for this as follows..

Decianax:
LSHIFT+4 --------------> S4A
LCTRL+LALT+K ----------> S4E
LSHIFT+LALT+K ---------> S4I
LSHIFT+LCTRL+LALT+K ---> S4O
LCTRL+K ---------------> S4U

Decianex:
LSHIFT+LCTRL+K --------> S4A
LSHIFT+4 --------------> S4E
LSHIFT+LALT+K ---------> S4I
LSHIFT+LCTRL+LALT+K ---> S4O
LCTRL+K ---------------> S4U

Decianix:
LSHIFT+LCTRL+K --------> S4A
LCTRL+LALT+K ----------> S4E
LSHIFT+4 --------------> S4I
LSHIFT+LCTRL+LALT+K ---> S4O
LCTRL+K ---------------> S4U

Decianox:
LSHIFT+LCTRL+K --------> S4A
LCTRL+LALT+K ----------> S4E
LSHIFT+LALT+K ---------> S4I
LSHIFT+4 --------------> S4O
LCTRL+K ---------------> S4U

Decianux:
LSHIFT+LCTRL+K --------> S4A
LCTRL+LALT+K ----------> S4E
LSHIFT+LALT+K ---------> S4I
LSHIFT+LCTRL+LALT+K ---> S4O
LSHIFT+4 --------------> S4U

In game Starfire is set to Shift+4 on each character's action bars. The macro for Starfire on each character is tied to the K key and is as follows...

/assist
[mod:ctrl,mod:shift,nomod:alt,target=Decianax][mod:ctrl,mod:alt,nomod:shift,target=Decianex]
[mod:alt,mod:shift,nomod:ctrl,target=Decianix]
[mod:ctrl,mod:alt,mod:shift,target=Decianox]
[mod:ctrl,nomod:alt,nomod:shift,target=Decianux]
/cast Starfire

When I'm playing Decianax, Decianix, or Decianox, and I hit Shift+4 everything works fine, all characters get the correct target and 5 Starfires begin to cast. However, if I target a mob with Decianex or Decianux and hit Shift+4, the other characters do not get a target. It seems what is happening, is when Decianex hits Shift+4 the S4E hotstring gets triggered, and LCTRL+LALT+K are triggered on the other characters, but the shift is getting passed as well. What this means is that the other characters get passed the modifier sequence for Decianox (mod:ctrl,mod:alt,mod:shift) and try to assist, but only Decianex has the target so the spell fails on the slaves.

The same is true for Decianux, rather than just the CTRL modifier being passed through the hotstring, the Shift from pressing Shift+4 also gets passed, and the assist target is Decianax.

There must be a work around for this, as it seems people do bind abilities to Shift+Key with this set-up. With 5 characters, dropping shift as a modifier in the assist macro unfortunately isn't an option, as there aren't enough combinations of modifiers without it. It doesn't appear that I can put shift on a do-not-pass list, unless I'm missing something. Anyone have an idea how I can fix this, so using Shift+Key works on all characters?
