I can appreciate the effort you put into your research and posts, however I would say that all classes are almost entirely balenced. You should play as the other 2 classes and you will see. I would say titan has the slightest advantage in most situations, warlock is in the middle with great powers, heavy damage, and self revive, then hunter has a slight disadvantage in most situations. It is a slight diffrence, and it is based off how you play. With the hunter you need to be a tactical player to do best. Also although you have about 100 hours played that is really not a huge amount in comparison to many other players. Play nightfall, weekly heroic on level 28, and do the VoG. Then you will get exotics.
