Oh I love to get to ask the questions finally!

Interact with target works fine on my Shaman.
Outside of 40 yards my characters will flip around and run to the targeted mob and stop at 40 and pew pew.
At any range and non attackable npc, when using interact with target they will run towards.
If the target is within 40 yards and the character is not facing the target. It will sit there until it is within 5 yards and then flip around and attack.
All actions being performed spamming interact key.

Does anyone have a fix for this? Or know why this happens? I mean it's workable right now, I'm just concerned about PvP and them not readjusting targets moving.
