I will have to agree that Hunters (the class, not the player) dominate PvP over other classes, but I wouldn't even say it's because of the super. I do a lot better on the Hunter than the other two characters, and the most aiding factors are agility, their jump, the ability to blink (which is nearly as annoying on a Warlock), the gun perks (Woe and Trance), and the ability to drop off the radar. In terms of grenades and melee (aka shotgun sub), I find Warlocks a lot more menacing. And Titan supers are the ultimate bitch, you have less time to react to it than any other super, and a very slim chance of stopping them from using it or dying in the process (within range). Granted how unpopular overall Titans seem to be, I'm surprised it surpassed Warlocks on the top 100. 14% is really low...is it because of the glide?
