This is my pistol shield build. It’s very nice even more so since the update as more single target ranged mobs. It slices through people in wvw just spec for precision and condition damange. If you want to be glass cannon go power, precision, condition damage and watch high burns and bleeds. You must be mobile or you will get squished.
