Destiny Beta: All 6 Subclasses - PvE Class Comparison

I'm having such a hard time deciding what I'm going to play, In almost every game I play I play a class similar to the hunter, an example being a soldier in mass effect. I just never really cared about spells etc.. But a part of me is really wanting to do the titan bc I know having a defender titan will help tons in raids. I feel alot more ppl will go hunter so I feel being a titan will be greatly accepted in a raid so that is why I'm seriously thinking about going titan.
