"Q-E"

"Q-E" (not official name) is a technique that launches you forward significantly.

It is done by: jumping and then immediately pressing [ q ](kick) and [ e ](roll) at the same time. (Its hard to do it at first, but after a while it becomes second nature).

 Why you would wanna do that: 

-Its good for gaining distance and preserve stamina.

-It unlocks new shortcuts.

-It can surprise your opponent if you launch yourself at them (and then attack).

Drawbacks:

-You have to wait for the roll to recharge, (which takes 10 seconds).

Basically "Q-E" is a separate technique rather than an upgrade to the roll, since it launches you further, but its less useful in close quarters combat (unless you're using it as a back-roll).
