Guild Wars 2

Is it worth traiting into both of these?

The idea I have is here:

using flame thrower, grenade kit, and a stun break for utilities.
thinking pistol/shield for weapon set.

Yeah, it’s really one sided, but in groups or in dungeons I’ll be at range the entire time. Is toughness or vitality even needed if the damage is high enough?

You could run glassy if you used your dodges properly. Traits that help with your endurance are quite readily available in glass builds. You also have a lot of crowd control should you opt for a rifle as your weapon.
