The new interact unit option.

[Barelan]

This has changed my multiboxing as well. I use it for:

1) Looting - I send my alts off to do simultaneous loots (now I CAN do collection quests )
2) Melee - it actually makes boxing melee work, I still ROFL when I see all my toon charge in to bash a mob (I use click to move with interact)
3) Facing. Hit interact, hit stop - all are facing in enemy.

I use Assist main, Interact with target (I have an option menu to select who does the interacting, with 6 being all)
