I consider NB archers very potent. You should really start to feel powerful by level 10. I normally use a rotation for long fights on pre lvl 10 quest bosses
1. Start from stealth using full power shot by holding the left mouse button.
2. Immediately release Poison Arrow, there are no cooldowns, so spam away.
3. Shadow Cloak to go stealth 2.5 seconds. This will make the boss stop in their tracks and will give you enough time for another power shot, followed by poison arrow.
4. Use scatter shot to knock back, or continue to use Shadow clock if you have not picked up scatter shot, yet.
5. Rinse and repeat until close to death.
6. Assassins Blade to finish them off.
I find with this method I will use Stamina and Magic evenly, so I do not feel like I am running out of either too soon. In most fights I am never touched, but if you do take damage, then using Strife and Heal potions will help greatly.
Also, don't forgot that you can still block attacks with your bow using the right mouse button and interrupt the power attacks with both mouse buttons. This will often stun the boss long enough for another power attack.
