I have been 2 boxing it but as last week I went to 3 boxing in Lotro. I was able to figure out on my own that for target assist to work correctly the character to whom you want the rest to follow must be the group leader and do all the invites.
Now question is how to setup innerspace so that I can get the minstrel character who would be for the sake of this posting IS3, to heal the others using F keys for the minstrel, I am a little confused on how to do it if its possible and was wondering if someone already is and how you have your keymapping setup to do it. My concern is that the other character in IS2 will target something else and stop assisting the group leader when fighting. At this point I am open to suggestions and advice.
