Just hit level 60! Give me a build to play to 80!
I like outputting damage, so like many engineers I went with a Grenade build. The Grenadier trait at 30 Explosives combined with the crits from Firearms is a fearsome combination. I also like 10 Tools just for the Kit Refinement perk (which comboes really well with Elixir Gun), but that can wait until you’re a higher level if you go with a Grenade build.
Stay with riffle and flamethrower, with critical/condition damage.
How many trait points do you have?
For general PvE, this is decent:

You can look at the traits and runes if you click the 3 gray icons above the Charr.
Flamethrower’s first skill is a 10 hit attack, and each hit has a chance to critical, so the traits I put in that build work very well.
For dungeons, change Flamethrower for Elixir R to revive allies without getting yourself killed.
If your team feel overwhelmed by enemies, change rifle to pistol/shield so you have the knockback and stun.
If you’re good with swapping kits, you can change Elixir H for MedKit, swap into it, use 5 for Fury, swap back to flamethrower. This way, you can drop Utility Goggles.
As for fun… engineer is always fun! (Ok, I don’t like grenades too much… I like the grenade skills a lot but I hate chucking grenades ;p )
For WvW… I haven’t been there a while, but I generally bring something along these lines…

Remembering to use MedKit’s 5 for fury, and condition removal.
