After careful deliberation, I've come to the conclusion that no class is "weaker" or more "OP" than the other. Why? Because it's all about [i]what your play style is[/i]. In other words, if you aren't doing well with the Titan you either need to, a) change your class to better suit how you play the game, or b) learn how to better play the Titan class. It's that easy.
