actually it kinda shows that youre competent at playing your class and when it comes down to it in such wz such as civil war, voidstar, and novare coast dps really does matter. if you have 4 people that can hit 400k damage in a warzone, those healers are gonna be easy to take down and so will the rest of their group which will allow you to cap a door or take a turret.
oh and by the way, he didn't say top damage he just said he hit over 600k worth of damage.
