I made 4 new warlocks, level 12 atm. I got a lvl 80 resto druid on the fifth account. I want the druid to be a healbot for the 4 warlocks while questing with them. It seems that he has to be grouped with the warlocks for any macro's to work, like:

/cast [@warlock#1] regrowth (in ingame macro's or in ISboxer)

or

/assist warlock#1
/cast regrowth

Anyone who got tips/tricks on how to get it done? Because i don't really want to group the 80 with the warlock, since that cuts the exp gained from NPCkills by ~60%. 34 instead of 94 exp gained for example.
