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.
