You can’t play a Dragonhunter Guardian in Guild Wars 2 right now no matter how much you might want to be wielding a bow and hunting the third most dangerous game (dragons are third, humans are second, bears with cyborg implants are first). But you can find out a little bit more about how the specialization will work with Dulfy’s summary of the most recent official livestream, which includes a detailed breakdown of the skills on display and several of the trait lines that Guardians will be able to utilize when Heart of Thorns launches.
As you would expect, several of the abilities have obvious benefits for fighting dragons, such as multiple projectile-blocking tricks from the longbow and the class virtues. The traps unique to the specialization are also detailed, with each trap having a short activation time and priming time before it’s ready to start firing; pre-placed traps are ideal if you want their effects to go off quickly.
