Shadestep does have a cool down. Clearly you have never used a hunter before. The Quiver is situational. It's essentially the Defender Titans suppression grenade as a super that has a higher chance of killing. I rarely kill 3 people with my quiver and I rarely see it happen. I use all 3 classes heavily they're all over 315 light. But of course I main a hunter. So no I don't have a bias opinion. When the Titan subclass was nerfed my Titan got the nerf also so before you call me a "huntard" or whatever you class war idiots say, I understand how significant the change was. It's ironic, Titans call Hunter's the "bitchy" ones yet most of the bitching I see is a Titan complaining about Hunter's lol. Get over yourself it's a video game.
