Fast Engineer
put 10 points into tools
I believe he is talking about leaps and dashes.
The closest you will get to those on the engineer are rocket boots, the 5 skill for the rifle, or the elixir guns 4 skill (which blasts you backwards).
We do have access to perma swiftness via speedy kits, however many builds, especially condition damage builds, do not take speedy kits as they need to spend the points elsewhere.
Mobility outside of swiftness is definitely one of our glaring weaknesses when you compare it to other professions. I believe the class was designed to be less mobile though and make up for it with more access to cripple or net.
Then again, some of the more mobile professions also have access to the same mobility reducing skills. I don’t know, I’m getting off point.
