I will agree with most people and say that the classes are each tailored to different play styles. I tend to do better as a titan due to my run-n-gun play style, and how I utilize flanking to FoH a CP on most of a team, as well as armamentarium giving 2 nades, which are always useful for capturing. Don't be disheartened if its not your best class, as you may just be better with another.
