Since the changes brought in from patch 3.1 with the new interact capabilities I now see how it is possible to multibox easily using melee toons. However, I'm having issues setting up a macro that is "leaderless" and actually interacts with an object.

Even with a basic:
/follow Leader
/focus Leader
/target focustarget

And then pressing the interact button does not always make my toons rush to interact. I have click to move turned on but this method is proving very unreliable. Is anyone able to help me make the proper macro for multiboxing using melee and interact?
