Is there a viable 1H Ranger build?

Returning player here and I've noticed while scouring build threads that there seems to be only "cut and paste" 2H build options. I am interested in building the Ranger I have recently managed to get to level 55 so it is somewhat a blank slate. I have no Dragan items and only a rag tag bunch of mixed gear of varying tiers.
Given that the Gwenfara Event is coming soon I was wondering what you all think of a 1H build Ranger using the event bow? I know that I will need supporting items, gajillions of gop's but this bow seems to make a case for itself. What supporting items would be ideal? Is this even a viable build?

 

Thats a really low amount of informations.
You want to play with 1H in PVE? Or just PVP
IF you returning player i assume you have this runes too..
So here is what i think match well with Gwenfara bow without Dragan.

• Whatever Amulett you see right for yourself.. Q9, Kramparus, Cube set amulett..
• Khalys cape, or Gwenfara, Nefertary cape..
• Q4 belt.. or Zeal
• Cube ring with some other ring.. maybe 2 Cube ring.. if you dont have Bloodtooth. But if you use cube ring then you should use cube amulett too. then you get (+15% crit dmg)
• Adorment is probalby magotina one, or Karabosa for more concentration.. but then Nefertary cape match well with Karabosa adorment. (5% more conc. + 5% more)
• Boots should be Q9 thats the only better one. Or Darkness Boots. Other than you can use Magotina boots, Karabossa one for set bonus with Adorment (+10% crit chance)
• For gloves get the Q7 one. Or Darkness gloves
• Grimmag torso.
• Khalys Shoulders.
• Khalys helm. Or Darkness helm
  
• Offhand is probably Heredur shield.

If you use 3 darkness set piece you get:

• 10,00% Increased critical hit value
• 15,00% Increased damage
• 10,00% Increased critical damage (from Helm)
• 2x 720 critical hit value which can be increased with leveling up the item. (Shoulders-Boots)

Or you can just use Cube full set, Blade dance bow with the similar buildup.
With the Blade dance bow you can get 55% Concentration costs reduce..
Thats not bad if you want to spam EA-s, Blade dance with +120 concentration or more..
One EA cost you 22,5 conc. with that Blade dance bow build.
Thats 4 EA in a row what cost you 90 conc, and lets count that you get 20 conc. from wisdom ,so thats 5 EA in a row.. Now we have the White Karabossa adorment + Nefertary cloak ,thats 2x +5% more conc.
Lets not forget that if you engaged yourself to play as much to wait untill the:

Therefor you can get a gem which boost you to get +5 conc.
Thats something like 6 EA in a row with Blade dance bow.
With Gwenfara bow thats 4 EA..
After that? Adrenalin! thats spice things up a little bit.
Of course only if you have atleast 5x 2% costs reduceing rune, Grimmag torso, Khaly shoulders, Karabossa adorment, Nefertary cloak for supporting items..

But untill you complete this set what i wrote 100% they introduce something better, or another Dragan event..
