Rogue range attacks

I’m trying to attack Nalak on Isle of Thunder and the rogue does not have an ability that can reach him. 32 yards is the farthest reach of any range ability, and that does not engage Nalak.

Simply go to the spawn point, and when he is near, throw a dagger at him to pull him down. I know for a fact you can do this on a rogue.

Poisoned Knife under assassination talent will work. Outlaw and subtlety do not have any ability to reach him.
