I've poked into this some more but the problem with lotro is that although you can do a few basic macro type things (follow and invite), they don't even have slash commands for most things. I can't find anything that works to promote to leader. /promote /lead /leader and a few other things all failed to do anything.

tomorrow when I restart my clients I think I'll try /flead but at this point outlook is doubtful on getting the swap the way I want it.

As I currently have my assisting work off assisting party leader (and following party leader) this is tres annoying.
