My quick-to-do Stamplar build for DB patch. Note on gear: I have left out enchants and traits. I will leave that to the individual user to determine what works for them. I will say that, personally, I prefer Stamina enchants on armor pieces and weapon damage enchants on jewelry.

GEAR
====================================================================================================
Helm: Engine Guardian - Medium Armor
Shoulders: Engine Guardian - Medium Armor

Reasoning: I like the thought of the Engine Guardian Set to help with sustain.

Chest: Hunding's Rage - Medium Armor
Gloves: Hunding's Rage - Medium Armor
Belt: Hunding's Rage - Medium Armor
Boots: Hunding's Rage - Medium Armor
Weapon (1st Slot): Hunding's Rage - Two handed Sword
Weapon (2nd Slot): Hunding's Rage - Bow

Reasoning: Hunding's Rage Set is THE go to for a medium armor, stamina based DPS. Use it.

Legs: Flanking Strategist - Medium Armor
Necklace: Flanking Strategist
Ring (Slot 1): Flanking Strategist
Ring (Slot 2): Flanking Strategist

Reasoning: Four piece Flanking Strategist Set provides more stamina, crit, and weapon damage. All things we can use.
