Obviously the good players can make any class look good. However, the middle of the pack players rely on cheese (like invisibility) to win matches. For example, my warlock has .9 KD this season and my hunter is at 1.65. That's a pretty big gap, and I quickly realized that I was at a disadvantage by playing warlock. Bungie even nerfed the arc melee, which was the one cool aspect of arc warlocks. I'm not saying to make them broken, but give us a few more tools to make them competitive.
