Based on the information that you have provided above, I would definitely suggest going with a ranger using long bow and a short bow so that you can always stay at range while using pets with lots of health to tank for you such as bears or drakes.
When fighting, send in your pet first and start your attack using bow skills that cause cripple and condition damage first followed up by more aggressive damage skills to finish off the mob. If your pet looses aggro, just kite around the mob hitting it when you can while your pet finishes it off.
Here is a possible build for you down below that is NOT meta. It offers a balance of damage and survivability. Be sure to swap your pets and weapons often to gain fury, swiftness, and might during combat. Also, try not to dodge so that you keep the 10% damage bonus. Since the idea is to stay at range, you should be able to just kite around without having to dodge too much. To remove conditions on yourself, use the healing spring or your brown bear skill “shake it off”.
Lastly, be sure to select gear with some survival stats on it like soldiers, dire, or carrion. However, if you find that you are able to stay at range without getting hit successfully, you might like to try some gear with more damage output.
