Goal of this build was to provide a ranged AoE build for Revanite Revenge Hardmode (EK HM). But what I quickly found out even thou this build deals decent AoE Ranged Damage using Devastation and Heavy Weapon AoE, the real damage came from DoT placement and how it scales easily even when not running with bonus Damage from Damage Stance. Note Heavy Weapons only have a 5m AoE.

Content Solo:
Sher Kar - YES
Revanite Daily - YES
Hracca Daily - YES

Pros:
64m Range with Heavy Weapons
DoT's can stack rather high for damage.

Cons:
Much of the survival relies on 2 debuffs and is only good 1v1.

Marksman: Goal here is to increase Dodge which roles over into Block.

Heavy Weapon Specialist: Juggernaut Jewelry Set for increase Devastation Chance. Lethal beam would provide yet another single target hit and does okay damage but I preferred to place points elsewhere. It Burns and Burn Down, take Burn Down may as well hit multiple targets vs just one target, they share the same timer.

Assassin: Focus on getting Savagery to increase Critical Hit Damage by 15%, this coupled with Citrus Snow (Food) and Jagged Edge (Expertise) this gives the build 39% Critical Hit Damage. Its a toss up between Citrus Snow as the build focuses more on DoT damage but for the initial hit Critical Hit Damage is preferred.

Combat Medic: Goal here was initially to get Thyroid Rupture, then I realized how much damage DoTs can do and started experimenting with various DoT abilities. Be careful with Nerve Gas it has a large AoE and may cause you to have more enemies on you then intended.

Commando: Armor Splash is amazing coupled with high Devastation, it provides a nice 1-2 punch to raw hits, when hitting clusters of PVE enemies you hit for 5-9k with normal hits then an additional 5-6k with Armor Splash. Then there is an additional chance to land a Acid DoT.

Doctor: The all important Bacta Ampule, one of the most useful quick heals available, doesn't hurt also to have a small heal over time.

Teras Kasi: I know this is a ranged build and Parry doesn't work with a ranged weapon equipped but Teras Kasi provides the highest amount of uplift to Block Chance. We also may want the Damage Stance and Tank Stance.

Beast Mastery: I run 1 Points in Beast Master this causes the build to have -25% Damage Output debuff to my character when a pet is out, its surprising thou how little this affects DoT Damage, I do not recommend thou turning Tank Stance on along with having a Pet out. Pets provide around 3-3.5% additional defense across the board. I highly recommend learning Enfeeble 5 from Krayt Dragons and training a compatible Pet. Enfeeble 5 deals a -20% Damage Output debuff to targets, this grants the build 2 abilities with -20 Damage Output debuffs, Thyroid and Enfeeble.
