My Damage Engineer build. Mostly for PvE, might try WvW

I have returned to the game and I have been looking over my build I have been working on for him. I basically made my Engineer forces on damages, both pure and conditions. What I like about this class is the kit so I like to focus on using the four kits I have got. I'm also thinking of giving the holosmith since I heard people don't use core and out of all of the other reminding specs, This one seems interesting and more damages forces. Now I would like to hear anyone's thoughts on my build and what changes I can make to it.

Oh in WvW that's just gonna explode, and not in a grenade sort of way. But I suppose you can catch blind people by surprise lol. Grenade and mortar kit doesnt really work in WvW. Flamethrower is... arguable. Running full glass cannon is certain death against most foes and you got very little condi cleanse on top of that. You are missing everything makes a holo such a strong fighter, ie all those knockdowns and power dps while having sustain traits.

But for PvE I guess anything works.
