Dueling doesn’t come from using a build. It’s more of a play style. You want to duel, you can do it on any build/class. Just duel more and now you’re a duelist. Sounds stupid but someone dueling in pvp knows their build well and knows how to manage outnumbered fights. That isn’t to say some do it better. Just play smarter and avoid dumb fights you know you won’t win or your team won’t win. Going down hurts your team more than you know. So if you’re out dueling a node and your team is failing miserably you’re going to have to help and peel key targets off the map like as soon as they leave spawn.
