The Titan hasn't changed the other classes have been made weaker in comparison as a result of the latest update. Nobody likes to be told how to play especially when you've been playing a game for basically 2 years. The developer decided that they wanted more players using a Titan. In order to do this the other classes would need to be made weaker so that the Titan would be the go to class. Play the game the way the developer tells you not the way you'd like to play it.
