I am not using follow but i have tried it. I did this ->

I made key 6 do
/assist character1
and key 7 do
/follow character1

In order to get the other character to attack with me i would hit 6 twice
then I would loot and hit 7 twice again for the character to follow me.

It seems tedious to do this everytime do you think I need more practice?

also I seen people with 5+ accounts accounts 1 lead and 4 followers. They hit a button and then all the accounts spread out perfectly before nuking a target down how is that done?

sorry I'm a pretty big nub and I'm stuck at work trying to figure this all out so when i go home I am ready to go.
