Unfortuntely you can't macro 'Interact with Target' yet. It only just appeared in patch 3.1 in the keybindings. Whether there will be macro support in the future or not, I don't know.

It's not a gimmick. Anyone who does not realise the potential of jump shooting has not played a hunter or arcane mage much imo.

As for a video.... erm..... how would I do that then? :S
