I use quite an unusual D/D condition build; it was adapted from what I used to PvE with. The build relies on high evade uptime for survivability. Damage comes from being able to rapidly apply long lasting conditions to multiple targets with deathblossom and caltrops. Sigils and runes provide additional conditions to conceal bleeds from cleanses.
Very good for flipping camps and quickly taking out small parties. Not so great at sustained fights due to a lack of stealth – definitely a struggle to fight bunker necromancers and P/D thieves.
