I'm using my own in-game macros for targetting, yes. ISBoxer basically handles only action bar paging when switching clients, I will jump and others will jump keybinds.

For now I use in-game macros, upon hitting F4/F5/F6 toons will follow as coded. I can't remember whether they follows or not during combat, they will autofollow after combat at least, but as far I recall strobing is not on, so they likely will not follow during combat then.

All I'm looking for is basically some sort of advises. What I could or should do else, because I definitely must do something wrong here.
Perhaps I explained too vaguely and you have a image in your head there's nothing wrong with my gamestyle and everything should work just fine.
Well, I can tell you everything is not going just fine, and I wish to get some help here.

Here's a bit more:
If rogue gets my toon which is at end of the 'train', I manage to turn my main toward rogue but not my 2nd toon, because I basically am using only mouse for moving in multiboxing,
because pressing WASD would broadcast it on other clients and that would not only move other toons but myself as well, and this is where everything goes wrong.
Sometimes when I try to adjust angle of my toons be it mouse broadcast or keyboard, they mostly end up facing at awkward angles and rogue gets easy kills.
