IS Boxer has no way of knowing what is going on in the game.
You can configure your options very intelligently, to do an awful lot in the game.
But it will have no way of knowing if a spell actually fired off (beyond, was the key sent to the game), whether it hit or was resisted, whether your toon attacked or could not because you were dead...

There is an option in Jamba to disable Strobe if any toon is in combat.
And to reinitiate it, as soon as combat ends.
And you can set the Strobe target to the leader, or to a different target instead.
If you're driving with the Healer, you could Strobe to the Healer after combat; assuming your toons were in Follow range, that could work.
If you were out of follow range, I don't imagine Strobe would be any different than /Follow.



I personally have IWT as a mapped key, that is sent to the current window only.
And have my melee toons in an Action Target Group, called Melee IWT.

Then send my IWT (via a Do Mapped Key Action), to the Melee ATG.

I also have a toggle (two-step mapped key), which enables/disables the Do Mapped Key (that calls the IWT to Current Window, for Melee ATG toons).

Effectively, I spam any of:
a) Howling Blast sequence; or
b) Obliterate sequence; or
c) Death Strike sequence...
And my melee toons will IWT whatever my leader is targeting.
But I can toggle that off... which is very useful when holding a choke point, and not wanting the team to move... or when fighting in an AV bunker and standing on the stairs, rather than running around the "donut ledge" and falling off the rim...

I also have movement keys which are only sent to the non-active window.
Which can be used to break movement, such as running off after the target is dead.
You can also IWT something closer to the healer, or in the direction you want the toons to move... provided it is a valid IWT target.
I have FTL Follow Me on a Mouse Thumb Button, which is easily accessed...

The running off is not perfect, but the controls are fairly good to curb/control that behavior.

For PvE, or when you don't want the team to move...
You can disable the integrated IWT, and still have the option to manually push it (on a different mapped key) for quest givers or flight paths, etc...
