All classes are balanced. They all have their own weaknesses and strengths. Hunter's have the most mobility. They are moving in and out of combat and shooting at everything they see or weaving through the thick of the fight with bladedancer mode activated. On the other hand our grenades are probably the worst of the 3 classes (in my opinion) and we can be killed during our ultimate's verily easily once you learn to counter it. Titans are the tankiest. They are always in the thick of the fight usually with a shotgun or fusion rifle and using their supers to take out a area of enemies or locking down an area with ward of dawn. However they are the slowest class and basically ALWAYS have to stay right in the middle of the fight so they put their selves at risk. Warlocks deal the most damage. They have the strongest grenades and deal the most amount of damage in the area making them big nukers. However they are incredibly squishy and die at the snap of a finger. I think of them as the 3 base classes of a lot of games. Hunter is a rogue class or a hunter class. Rogue being a melee assassin bladedancer and hunter being the range gunslinger. Titan is the warrior. A beefy person in the front lines. Warlock is the mage. Weak defenses but strong abilities.
