Nightfall Pve Build Help

I have decided to start a ranger in the nf campaign, however I am not sure what skills to acquire as I level. I was thinking mostly marksmanship. I would appreciate any help or input.

This is my favorite build at the moment and is one of the most effective I have found in a while:

[skill]Crossfire[/skill][skill]Savage Shot[/skill][skill]Apply Poison[/skill][skill]Burning Arrow[/skill][skill]Mending Touch[/skill][skill]Natural Stride[/skill][skill]Troll Unguent[/skill][skill]Rebirth[/skill]

Burning Arrow is a very good elite skill to add to overall dps and synergizes well with poison. Mending Touch is a rather optional slot and should be adapted for utility. If you are going against a lot of hexes, then substitute [skill]Holy Veil[/skill] or your hex removal of choice. If you will be confronting a lot of straight melee, then [skill]Throw Dirt[/skill] can be nice as well. I found that at the end of Nightfall when I encountered a certain boss (kept anonymous to prevent spoilers), it was advantageous to use [skill]Pin Down[/skill] so that the group could take care of the bonus before finishing off the boss. One point to note, however, is that you will want to run with 14 expertise in this build so that you can maintain energy management though long battles. If you still find energy problems, then switch Savage Shot for [skill]Distracting Shot[/skill].

^ Yea I usually run a Superior and Major to get a 14/14/9 spread on the above build.

Thank you very much for the help.
I'll be sure to use this build

I've considered, after the istani island, to go to the kaineng and do the factions stuff, should I get rit as my secondary?
