Ranger DPS... HELP!!!Follow

Ok I have a level 80 Fae Ranger and I love playing him, However in groups I tend to be right in the middle of the road when it comes to DPS on a named mob, but a bit higher on "normal" mobs. Are other classes skills just that much faster that they can burn through the skills? I guess as far as the heirarchy of DPS is concerned, how does the order exactly go? I think it must have something to do with the order that I use my skills and the way that I chain them together. Most of my skills are adept 3 or higher, I am using the best poisons, the best bow that I can find, and my melee weapons are highly rated. I went AGL and INT trees and then multi-shot and poison trees. Am I overthinking this because of the debuffs that some ranger skills have built in does that greatly increase the amount of dammage other classes do. In short I am trying to get the most out of my character and would like a little insight.
