During a pvp match I watched this one guy engage 3 on 1 or more odds and just keep killing until he was close to death then he would just full impulse away.....

Made it impossible to kill him as he would always run away and it was very fast so you could not follow...or finish him off, he would just repeat this with others so you could never kill them but they could always kill you.....

What skill is this that allows you to go full impulse speeds in the middle of combat? and what genius thought this would be a good idea in pvp?
