Guild Wars 2

I’ve recently switched from Ele to Engi as a main and I’m totally in love with this class, my favourite kits are without doubt grenades and bombs as I feel flamethrower just lacks damage.

I’m looking to build full celestial stat gear as I think the raw damage and the conditions nades/bombs offer will fit perfectly with the celestial stats plus it offers extra survivability with the bomb laying.

Is this build any good and if anyone has a similar build could they tell me the trait lines they follow and if they go with pistol/pistol or what?

30/0/0/10/10 is a very solid base for any PvE Grenade Kit Engineer build:

Pistol/Shield for Blind, Block and blast finisher or Rifle for raw damage.

Here is a very functional build that I have used that fits the P/S + Grenades + Bombs that the OP mentions.
