I played archer and solo'ed leve's a good bit. And I had really no issues living. And this was starting as an archer. If they keep close shot all you do is pretty much stand with in the basic range hit it with 2 arrows use close shot de target it to run back a bit and fire at it and use a ws skill.

In WoW I play hunter and even with AA i just spam my light shot and the shot that gives some focus back. (then again also no arrows so no need to worry about money)
