like for example going 10/30/0/0/30 build
explosive 10
firearms 30
tools 30
I’m guessing your intent here was to maximize precision and crit damage?
It’s usually best looking at the builds in terms of major trait choices and utility skills rather than the attribute bonuses you get from allocating your trait points. The attribute bonuses are still important, but they usually aren’t what defines a given build itself.
If you did want to focus on critical hitting, you might try looking up something like static discharge builds, which can put out very high burst damage but have little in the way of true defences. It’s probably one of our best builds in terms of high raw damage output.
However, the engineer tends not to be the king of spiking with direct damage like a thief, warrior, or mesmer might be. As such, you might have something that is a bit underwhelming if you focus solely on boosting your critical hit potential (% chance and % damage).
That said, we do have a number of on-crit effects that can occur via traits to apply various conditions. Some of our strongest builds for damage output focus a lot on condition damage, so you might try considering that in your build too.
Unfortunately, I don’t think there’s a nice centralized place to read about people’s builds, but if you search around the engineer forum for awhile, you’ll probably find some.
As an example, this one focuses on bursting using the bomb kit: http://en.gw2skills.net/editor/?fcAQFAUlIqic3zSfF1LJxoCdGkC76XRKqMl/oQusF;TgAg0Cno4ywlgLbNOukcB
I don’t remember where the video for it is, but the basic idea is to place your Big ‘Ol Bomb, pull them in with magnet, jump shot them after they’re pulled to you, and hit them with your other skills once they get blown away by the bomb. This build can work with high crit chance and damage with high power (i.e. berserker gear) since most of the damage will be direct damage, and the utility skills include some of our hardest hitting direct damage skills.
