Ya I'm aware of how you named your chars and thought it was brilliant. But I also dual/tripple in 5 mans where I may be the tank and primary healer so that isn't an option in that case. Macros could work but would require a lot of juggling and looking around... "Ok right now GroupMember4 on main box is GroupMember3 on off box <update macro> crap he left and new player arrived that drops the order!"

I wonder if Ora could help, assign by Main tank order, it self syncs and there's a target by tank box already I believe.
