you want your gear and weapons to be part of item sets, which boost your stats quite a bit. try to boost stamina and weapon damage. if you can increase weapon critical as well, thats a plus.

on your 2H bar use rally. it increases weapon damage by 20% and gives you a strong heal. drop coagulating blood and slot in rally.

remove charging maneuvers from one of your bars and find another good buff. evil hunter might be a good one to put on your bow bar if thats what you mainly use.

2H sword is going to be better dps than a bow. If you are more concerned with doing more damage rather than sticking with your bow, I would recommend fitting executioner on your 2H bar and using 2H as your main damage.

Also, im not sure of your attributes but if using 2H and bow, you want your attributes and gear enchants to be mostly stamina.

MORE STAM = MORE DPS

hope that helps a little.

Your gear seems okay, but your skills could use some work. You have a couple skills on both bars that are wasting space and hardened armor/unstoppable both give you the marjor buffs so pick one of them. If you mostly use bow then use your sword as the buff bar. Take off unstoppable and charging maneuver from the bow bar. Add a arrow spray morph for AOE and another skill that you like.

For the sword bar take off coagulating blood and add rally, this will give you a HOT and damage boost, keep this up at all times. I wouldn't recommend using both brawler and dizzying swing as they are both just damage skills, you only really need one, especially if you don't use your sword much. Take off one of them and add crit rush or another skill that you like.

I also recommend wrecking blow over dizzying swing, it gives you a damage boost to your next attack. An execute might be a good idea also. You could move hardened armor or maneuver up to your bow bar and add executioner from the 2h skill line. Not only is it good for finishing off enemies but you get extra stam regen from the 2h passive.

So...
bow - coagulating blood, venom arrow, leathal arrow, arrow spray(morph), open(your choice) / ww (something different from other bar)

2h sword - rally, dizzying swing(or brawler), crit rush, hardened armor, charging maneuver. / a different ultimate.

sets matter in pve also. you dont necessarily need to craft the items yourself. if you look around in guild traders you could probably get some decent v9 sets for cheap. it would make a world of difference. that may be your whole issue.

good luck

You're quite lacking in stamina. I think you might want to put a couple more points in it.

I've been using Rally and I perform infinitely worse now, i'm actually dying 3/5 times instead of 1/5 when I could self heal and usw potions to self sustain

I don't have enough traits learned to even consider crafting it yet

I also haven't been investing in any of the guild skill lines, which means no Dawnbreaker

UPDATE:

Switching to the Ashens Grip set has been utterly amazing. Who knew?
If I get to respec my skill points, i'm dumping my Magicka into health and stamina.

To add to the dumping magicka...

You can still boost your defenses a good amount by using only igneous shield or spiked/hardened armor and Rally/Momentum.

So before you jump into a group of enemies, use spiked armor OR igneous shield, use Rally/Momentum (same skill, one is a morph of the other) and then start attacking. The damage shield from the armor/shield should be enough to keep you from getting wiped, and the heal from rally/momentum should be enough to keep your life up in case you do get hit pretty hard. Also, if you decide to keep Brawler as an AoE with the added damage shield thats a great way to keep yourself allive! Just remember that this would be most effective with as much stamina as you can get (enchants, extra points etc..) so you can spam it a bit and still have enough stamina to finish off the enemy with some burst damage.

Those are really the only utility skills you should need WHEN you manage to get your base DPS up. If you think your damage is still lower than you'd like I would say you are perfectly fine running Dragons Blood on your bar as a heal, especially if you are sticking with mainly PvE.

Also, its never a bad idea to pick up all the health pots for your level from fallen enemies. Having an "Oh *** Potion" in the quick slot has always found a way to help me in a sticky situation.

All in all, the DK is a great class with so many skill combinations that work in PvE just keep messing with them and see if you find a better set up that you enjoy.
