I beg to differ, a blade dancer hunter can turn invisible just by crouching, if he gets behind someone or even uses his/her arc blade skill he would kill any class, warlocks on the other hand aren't meant to take only one enemy but instead many, they can deal massive damage to a group of enemy's. Titans can take damage and kill 1-3 people with one blow, each class has a different use, but they all use guns. Don't give one class all the credit of being the best, they have different uses.
