Tank pulling mobs unwanted auto attacks, how to turn off?

[GhostintheShell]

This auto attack is very confusing because in the new Auto-use supplies UI interface that has Auto Next Target, everything is off.  With no macro on, merely just running to pull mobs like I always have in the past, if I were to use a single AOE attack skills, my tank would keep auto attacking even though my mouse click is clearly to get out of the harms way to agro the mobs back to my support party.  Is there a way to turn this off when we want to?  I can imagine there may be instances where we would want auto attack....  If this is not fixed, i can imagine certain deaths due to the fact your intention is to pull mobs to get out of the harms way, yet you're attacking full force without any of your supports nearby.
