Guild Wars 2

So I made an open world PVE build. It would be nice to make it viable for dungeons. Not really sure what I was aiming for here but how well would this work? I’m not really that great at this sort of thing.

I’m thinking of swapping out Speedy Gadgets for Kit Refinement or Speedy Kits.

Thanks for the advice everyone!

Looks more like a pvp build to me.
If it really is a pve build, why aed over healing turret? No bombs/grenades either?
In my opinion self regulating defences and automated response are a bit of a waste of trait points when it comes to pve.
You thought right to use speedy kits. It’s basically a permanent 33% movement speed increase.
Kit refinement used to be good, but ever since the great kit refinement massacre almost nobody uses it.
Lastly, what type of pve are you building for? Open world or dungeons?

I’m mainly building for open world PVE, although it would be nice to make it viable for dungeons too. I chose AED over Healing Turret cause it looked like I could get more healing out of it if I used it at the right time. I didn’t take bombs/grenades because I wasn’t sure which kit I should use so I just chose a random one. I swapped out Elixir Gun for Grenade Kit and also changed some traits. Here’s the new version.

Thanks for the advice.

1. Healing Turret is a staple healing skill in pretty much all modes. You generally only want to go Med Kit if you are running solo and a lot in tools. You never want to run Elixir H or AED as they provide less healing over time and less condi clears over time. Even in Might stacking builds, go healing turret. It’s that good.
2. You’re giving yourself way too much defense. Conditions in PvE are fairly rare and generally non-threatening. Taking Elixir C, Automated Response and Elixir Gun is total overkill in that department.
3. You really lack damage in this build. Rifle alone is not that good damage, nor is Elixir Gun. The true key to great damage with an engineer is taking a bunch of skills that deal high damage and swapping between using them. I highly suggest taking grenade kit and/or bomb kit in addition to elixir gun. Elixir Gun’s acid bomb hits really hard in power builds. Flamethrower can also be fun and synergizes with your traits in Firearms. Focus mostly on using skill 2 in flamethrower if you take it rather than the auto attack. Drop Elixir C and Rocket boots for this.
4. Mortar is only barely passable in one situation: Enemies are coming to a predetermined location that you must defend and have the ability to pull you to them. Even in this situation, Mortar is very buggy and will often stop firing even when you hit the buttons, putting them on a FULL cooldown. Take either Elixir X or Supply Crate. Mixing Elixir X with Big Ol Bomb (The toolbelt skill from Bomb Kit) will do crazy damage (12k+!). This is because if you get tornado from Elixir X, your power goes to insane levels (double!). Supply Crate is just great all around. Fantastic CC and drops bandages that can heal for about 1k each.
5. If you want to deal damage in PvE, going deep into the explosives line is highly recommended. I always go 30 into that line for PvE for grenadier. If you want to go completely damage, go 20 into tools. Speedy Kits is an amazing trait and always prepared is good in stacks if you happen to go down (heals allies if you move a bit). If you take Tool Kit, Power wrench is amazing. In Alchemy, Deadly Mixture was a great choice. I suggest keeping that and taking both flamethrower AND Elixir Gun. The final build would be something like this:

This

Now you have extremely high damage, very high power, and support:

1. Support – Healing Turret, Super Elixir (Elixir Gun), Supply Crate
2. Damage – Flame Blast (Flamethrower), Grenade Kit, Rifle 3 and 5, Acid Bomb (Elixir Gun).
3. Control – Net Shot, Overcharged Shot, Air Blast, Supply Crate (Stun and Net Turret).

I’ll just link the build I use

Works well enough for me in dungeons/open world.
Just a warning, I wouldn’t go spending a bunch of gold on runes and sigils just yet. Wait till the 15th rolls on by when runes/sigils are rebalanced.
