As far as follow breaking, welcome to WoW
Combat-wise, WoW breaks auto-follow if you melee or use a channeled spell. If you avoid landing a melee hit or using a channeled spell, you will remain following during and after combat. Interact with Target will break follow because of Click to Move (though you don't appear to be using ISBoxer's IWT, so I don't know what you're doing to break follow at the quest giver).
If re-following is a problem for you, the Jamba addon has a follow strobing feature, which attempts to re-follow every second (or something like that). If you have Jamba enabled, you can hit Shift+Alt+F to toggle it. You can also change the Hotkey for FTL Follow Me to be something other than Alt+F.
The universal invite macro is generated for one Character Set. It looks like this:
- Code:
!if ("slot 1" and character is not "slot 1") /invite {SLOT1}
!if ("slot 2" and character is not "slot 2") /invite {SLOT2}
!if ("slot 3" and character is not "slot 3") /invite {SLOT3}
!if ("slot 4" and character is not "slot 4") /invite {SLOT4}
!if ("slot 5" and character is not "slot 5") /invite {SLOT5}
You are linking two Character Sets, so this method won't work correctly for you. What you can do is modify the invite macro to invite specific characters, so it looks like this:
- Code:
!if ("slot 1" and character is not "slot 1") /invite {SLOT1}
!if ("slot 2" and character is not "slot 2") /invite {SLOT2}
!if ("slot 3" and character is not "slot 3") /invite {SLOT3}
!if ("slot 4" and character is not "slot 4") /invite {SLOT4}
!if ("slot 5" and character is not "slot 5") /invite {SLOT5}
/invite mytoon
/invite myothertoon
/invite anotherone
To do so, in the top pane select World of Warcraft under Game Helpers, then in the bottom left select /invite team. On the right, add additional the lines to the Commands box. After you Export, you will need to "/console reloadui" in the game in order for the game to reload the ISBoxer Addon (which handles the WoW macros).
