Running Demonic would only be useful on fights like Tich or Skorp with a lawlbeam spec imo. If you have bracers I'd run bracers with ring for the rest of this patch with bloodlet, if you don't have bracers run chaos cleave or first blood both are good, I personally like CC. You have good crit, mastery, haste. And Chaos Blades out performs demonic by a lot on most fights. If you want something to compare to here's my DH parses, I'm not a very good DH, but just letting you know what I run XD. https://www.warcraftlogs.com/rankings/character/16002121/11#difficulty=4&class=DemonHunter&spec=

Also, check Ask Mr Robot with your armory updated on it to Sim single target Ursoc. It will give you an idea of how much damage you should be able to do.

From looking at your armory it says you don't have Blessing of the Ancients. I use that talent instead of Shooting Stars. Also what are those trinkets? If those are your dps trinkets, that's why your dps isn't good :P, but from looking at your logs you have Swarming Plaguehive. Your neck doesn't show being enchanted, but logs show Satyr.. so It's hard to tell since your armory isn't updated. Are you double potting every fight, using food, and a flask? Didn't go too far into detail with your logs, just looked at the dps and your gear. http://us.battle.net/wow/en/character/lightningh
