Ok, ok, at first you're thinking, "how is a detaunt attack helpful if I have to be behind the mob?" Well, you have to be proactive about shedding your aggro. "But I'm half a block away raining death down from above" you say. This ability isn't available to you in Scout Stance, only your new Assault Stance and another one down the line.

In later levels, you will get a short term, long cooldown Vengeful buff that will activate special functions in certain abilities like this one.

Level 5 - Takedown
15 AP, 1sec casting, 5-65ft range, 15sec cooldown
An Ailment which deals 41 damage and snares your target, reducing their run speed by 40% for 10 seconds. If you are Vengeful, then the target will also be knocked down for 3 seconds.

Don't have time to get off your arrow attacks before the mob closes in? Open with this snare then you'll usually have enough time to fire your Broadhead and Acid Arrow attacks before having to switch to Assault Stance.

Next, an examination of levels 6 - 10 including Skirmish Stance (ranged close-combat), a real detaunt and very big arrow attack.
