Engi build for wvw havoc roaming?
You will need run warrior if wat all those 3 things at once:-P
Tekkit’s Workshop
Hmmm… bomb kit is very good for aoe and melee situations, and with regenerative backpack and elixir infused bombs you can have some pretty nice heals, but that takes a lot of trait points. If you wanna survive, I’d say gear shield from tool kit is a must. As for damage, if you wanna do damage, yet have good aoe damage and survivability at the same time, you probably need to go the condition route.
I find that surviving is less about gear shield (often not always) and more about having a way to reset the fight.
I typically will run grenades, bombs, and e-gun or rocket boots for havoc.
Antitoxin runes will help with survivorability.
You can switch between +cond duration food for damage and -cond food to shrug off many immobilizes.
Typically run 6/2/0/4/2 but if the fights are a bit too hot (outnumbered) move to 6/0/0/4/4 and pick up leg mods and remember you ALSO have all your toolbelt skills reset at 25% so use all the heals and regens!
In short, find a build you can quickly switch just a couple of things out as you start to realize what type of fights you will have for the night. Best advice for an engineer, I think.
