I'll actually have to sincerely disagree with you, or simply respond by saying that it is in fact just you. It must be the way you are playing the Crucible that may need a bit of alteration. I actually switched from the Warlock class to the Titan class as it better suits my play style. It all boils down to the manner in which you game. Warlock is strategical and requires much finesse. Titan is about brute force and powerful defense. Hunter seems to reflect circumventing, wherein the revolving around the outskirts, and penetrating tactically. Think of it as Titans on the frontlines, Hunters on the outer limits, and warlocks on the backend. And I hope no one thinks I'm detracting from their classes. All are viable options, and they all have their role to play.
