Guild Wars 2

so after playing revnant during bwe1 it has enspired me to try a dps healing build. luckily thiefs have traits that help with this. i have tested in pvp and pve, pve seems to work the best especially in dungeons, fotm, and world bosses. due to lack of resources cant complete builds for testing but its quite fun. im trying to find a fine balance between healing damage and toughness or sustainability. if anyone would like to help test it the build is below:
Gear: testing zerkers gear with clerics/nomad trinkets(would like suggestions for gear)
Weapons: Sw+p/bow (both with a sigil of accuracy because you heal from crit damage)
Sw+p pistol 3 skill will be your heal skill and dps so only hit this if you are taking damage other than that you want to auto
Traits:

Critical strike: Side strike or Flawless strike, Practiced tolerance, Invigorating Precision( for healing from crit damage)
Acrobatic: Pain response, Hard to catch, Assassins reward (heals you from spent initiative)
Trickery: Thrill of the crime, Trickster, Sleight of hand

Utility skills:
Signet of malice(heals you every time you do damage), haste,
(i like to choose 2 of these 3 [Signet of shadows/Infiltrators signet/Signet of agility])

Elite skill: dagger storm

if anyone has any suggestions to make this work for better in pve or to make it work pvp and wvw it would e greatly appreciated im really like playing this build and would like to see it work nice.
