Guild Wars 2

I love the Engi as well. From the skills, to the playstyle, to the very concept of Engi. Just awesome.

I call my Rifle Whispering Joe. Or Bob..

Na. You can run up to them instantly after the overcharged shot and using the goggles. Blunderblussing them as they’re down. As I said, the Utility Goggles straight after the overcharged shot cancels the stun you get, so basically you can Overcharge shot whilst moving forward.

Dunno if this is common knowledge, a bug, or useful at all, but any technique is better than none.
If you’re using a Rifle and some sort of stun breaker, preferably The utility Goggles, you can instantly break your own knock back from the Overcharge shot. This could allow for a Jump Shot, or Blunderbuss right off a Overcharged.
