I knew this but never really found it useful. Maybe I'm wrong though. I use to think sliding was useless but recently I've see people in pvp sliding and actually getting a lot if kills. I started using my fleet foot ability on my hunter and turns out sliding is awesome. Doesn't work every time though. It's if your running and an enemy pops out in front of u and you know your too far away so u slide to cover the distance then BAM. clutch
