U can change [Stretch] to [Umbral Vitality]

Sometimes it's time for a change and maybe its a good option to start with some information about my Playstyle and Weapons.

At first nice that you are intrested in this build its quitly fun to play.
Personally i choose a lower Range and a lower Efficiency for an higher Strength. If u play in a Team u can easily survive by jsut keep jumping, but then u have a higher range.
Useful is a higher Range also in a group who had someone like [Volt] because it could be that you are too fast to get your own Motes. Also im a big fan of an higher Duration.

Possible Changes i use:

• Strech could be a [Umbral Vitality] [in this Case it would be more efficiently if u would use an Umbra Forma instead of an normal Forma, maybe
  instead of an Naramon Polarity, swap some Modslots or use a classical Continuity
  -The Arcane-Slots are free to choose but i decided to go with at least energize

[Wisp]

Passive Ability

[Wisp] is like the shadow in the night you didn't see. She use her passive ability to move invisibly.
As long she uses silent Weapons she will be your Assasin in the Night how kills you by jumping next to you.

Note
Please avoid hard landings and loud Weapons if u want to stay the unseen.

Reservoirs
The Reservoirs are a very nice thing. They boost yourself and your Team if they want
Vitality-Mote
-Mote granted more Health
-Mote granted Health/Sec
Haste-Mote
-Movement Speed
-Attack Speed/Fire Rate (Fire Rate is highe then the other)
Shock-Mote
-Stuns nearby Enemies

Wil-O-[Wisp]
Send a Projection of yourself in a Direction. If u would recast this Ability you will take the Place of the Projection or better you Teleport.
After Teleport you get 3 seconds invulnerability. If you hold "2" the Projection travels much more faster and if u release "2" you teleport.

Note
Don't ignore this ability
-You get a short time Invulnerability
-You can travel much faster and skip somtimes some longer ways.
