You sir are not playing Titan right
People play hunters and warlocks because they want it easy and get easy kills. That's why you don't see many titans in crucible because people press the easy button.

The easy button is the Titan panic button. Reason Titans don't do well is to often they use their super for a single kill because they are getting shot. Instead titans need to learn to time supers for max effect. As a hunter super animations are an easy way to get killed and timing is crucial.

My titan doesn't have a panic button let alone buttons on him. Don't know where you getting that from. And it's rare for a Titan to actually get a multi kill with a super as you have to be up close as for a hunter and warlock it's easier you can kill from range. I myself love using my super on a Blade dancer alone,stops him from killing my whole team. Not a "panic" and is used wisely.
