I would suggest going with the default FTL targeting which is built in.
That frees your Focus, Target and Party Leader functions, and still allows any toon to lead and the others follow/assist properly.

If for a specific encounter you want Focus or whatever.
You can easily use a warcraft macro that targets Focus, or even modify the FTL stuff to not FTL Target for some keys.

Being able to insta-switch toons, and lead with anyone (if one is cylconed or whatever) is strong.




Definitely set up slave independent movement.

You could duplicate/copy the "Others Jump" keys.
Target: Window all without current.

You could also have a mouse thumb button or easy to push key.
Make it a two step key.
Which activates the mouse (same as repeater basically), with a target of the not current windows.
And deactivates on the next step for the same targets.
Then set it to execute on press or release.
Which is cumbersome in that your toons won't be sync'd entirely, but mouse turning is far faster then keyboard turning.




You'll want an IWT type key.

Again two steps, executed on press and release.
Probably for all windows.

Press = IWT to everyone.
Release = Down Arrow to everyone, which breaks the IWT movement.
Need to set it to hold keystrokes while the key is held.

Then you can press the key, to recover from a Fear Bomb.
Hold it until they're closer to the target, ie, regrouped.

Or when someone runs to the far side of your group press and release quickly.
Which has them IWT (face and begin moving to the target) and then break the movement fast.





That is your basic software turning/facing options.

Melee in the group is always going to suck... and you don't have all of your tools to deal with them yet.

Dropping Magma Totems and doing Fire Nova can make it painful to be close.
Thunderstorm can send them flying away from you.
Stoneclaw, especially glyphed is a damage absorb shield.
Earthbind can make re-closing slower, while you nuke them, and has a chance to root them in place.
Then you do Thunderstorm number two; and number three after that.
