Description:
Prep yourself with apply poison, and then use crippling shot on any warriors running at your team. As they hobble towards you, use hunter's shot to increase their degen, and then use crippling shot on all of your other enemies.
Watch casters and be ready to use savage shot or distracting shot, as this is build actually provides you with some good interrupt ability. Try to use distracting shot on quick recharge skills, and savage shot on long recast skills, to disable your enemy as much as possible.
Use troll unguent if your health starts to go down, it is a skill best used when you are still in the 75% range as it is only health regen and it has a long casting time, and thus is not much of a last second save kind of skill.
And of course, use storm chaser in conjunction with crippling shot and hunter's shot to stop enemies from attacking you while lowering their health.
It's a fun build to run, just now all of my teammates were dead and my resurrection signet was used up... It was me versus two level 20 melee characters and a level 18 elementalist. I used some tactful running, and after a few minutes of slowing them down, degenerating their health, and interrupting their self heals, I was able to take them down... Of course they spewed random words to me about how I was a no good runner and such, but I wasn't just running to piss them off... I did win in the end, and not by them simply leaving!
And lastly, I know this build has been done before, even possibly in a very similiar manner, so I'm sorry I cannot credit whoever originated it, but I thought people should know about it.
