Taunt on Kalecgos

Last night my guild attempted kalecgos and i was assigned to take the first portal down to the demon but when i got down there it would not let me taunt off the NPC .

/cast [target=target,help] Righteous Defense; [target=targettarget,help] Righteous Defense

is the taunt macro i use. Any advice or changes i need to make to make this possible or just let another tank take the 1st portal and i hit up the 3rd one.

theres about a billion zillion other things about this

search ftw

click on npc
hit taunt spell not macro
profit
