I use this build and it’s very fine for roaming or running with zerg. But you have to master sword skills, learn and get used to it. You will never have a problem when 1vs1 or small group fight in wvw because you can run away all the times with sword skill#2,3 and dagger skill#4, use the skills wisely to avoid enemy’s skills while running away.
The most class that I have a problem with is the skilled thief players because they have mobility that can catch you faster than others class while you’re running away, so you have to play carefully when you encounter them. Conditions is the problem too but
you can handle by healing spring.
