I play as a hunter an ill tell you, Titans are the class I hate dealin with the most. Their panic super nails me all the time and that shoulder charge has had me almost throw my controller. The bubble is an awesome super that if strategically used can give your team a huge advantage. Their grenades can be a huge pain is the ass for me as well. Just keep working and try to learn a playing style that works for you. Remember, there is NO CHEESING IN THE CRUCIBLE!!! People will complain about any load out or strategy that you use that doesn't let them massacre you. Don't listen to all the clucking hens. Play how you enjoy playing.
