Without using guns the only offense you have is your grenades and punches and super. Titans have the Strong's punch and grants a over shield and there grenades may not be as powerful as the warlocks but are more strategic (blinding effect). Then the super. When the blinding helmet is equipped a titan can control a zone with ease, plus this class can make a lot of ours especially when all you are doing is punching. Warlocks supers have the potential to control zones but enemies will still shot at you when standing in your vortex/solar grenades.
