I'm a Titan, and I use Defender Subclass. I'd like to believe I'm pretty good. My k/d would be higher but I did AFK crucible once to see if I'd get better gear. :( seems like the best class for crucible would be blade dancer. I've probably died the most from that class. Edit: I'm a penis, but people call me an asshole. both actually. Make up your minds. They both look entirely different.
