Hey, Archery player here.
For PvE: I recommend Ranger with an Obsidian+ Shortspear and Dagger (offheals for days). You have decent CC and AoE with a Bonewall>Missile Rain>Skewer combo, which is good for grinding early on (if you're playing mostly solo.) Having two weapons gives you the Dual Wielding buff, which gives you a free 111 Attack Speed. The dagger proc further increases attack speed, while the spear proc ignores all armor, and has a 10% chance to proc (essentially another free critical hit, on top of your already high critical hit.) The only problem you really have with this class is that you have no ability to remove CC's on yourself, except with blessing. Vitalism also munches mana. And you only have back drop to aid you, along with stealth. (Though Backdrop>Throw Dagger>Charged Bolt is a free stun, if all of them hit.)
PvP: I highly recommend Primeval. Archery has good range, nearly no cast times, and a focus on kiting. Auramancy and Shadowplay feed that playstyle quite a bit. Trickster is much better suited for PvP groups, as you can essentially CC someone for at least 20 seconds. But both have rather poor AoE damage. I recommend double daggers all the way, for twice the procs of speed boost to sustain high DPS. Regardless, though, you can use an Obsidian Shortspear as well, which gives more versatility. And if you're not able to hurt a higher gear player, attack speed wont help as much a essentially hitting max damage 10% of the time.
Oracle is a healer build, and can't fight too well on their own. It's more like an off class of healing with your DPS coming in when you need to move. Problem with this, though, is that you'll need a staff for magic damage, a spear for ranged and healing. It's better to stick with something that can focus on one thing at a time, instead.
But regardless of your choice, you need to know that the only way to not die in PvP is to not get stunned by Darkrunners. Auramancy removes stun, and gives you the ability to teleport away from dark runners.
Really, the main problem is Darkrunners in general. It's too easy to kill anyone and anything as a DR.
