[etansb]

I have 2 chars grouped, Im hitting start with raf combat assist selected.

HB says I need a leader in the group?

 

[Tony]

you must chhose grinding mode for the leader of the party and Raf mode for the slave

if the toon you're selecting raf on is the leader it will in fact tell you this... simple solution, promote the other toon to leader of the group...
