Boxing Melees Question

[~Sanjoin~]

Hi
I was boxing shaman and other mixed teams a while, I love my paly tank, 4 shamies.
Now I wanted to try something new, so I decided to box 4 DKs and a priest.
Setting up the macros and so on, no problem.

But how do you manage to do the interact with target stuff without ending with all your guys running circles around a mob and then running errands all over the place after it's dead??

The only way I figured out , was to play one of the melees instead of the priest as main and press follow as soon as the mob is dead ...

I know, it's basics .. but maybe someone could give me a hint

thx
