Deepwood Snipers seem to largely focus on increasing the critical properties of their arrows, making them Keen and improving their critical multipliers. They also have abilities that allow them to Aim (adding bonuses to hit), use poison and reduce their target's concealment.
I don't remember for sure, but isn't the big ability of the deepwood sniper increased range increments? Not that applies in DDO...
