In fairness, I love all three classes (and actually restarted my Warlock and Hunter who were both mid 20's so I can play them alongside my wife). Yet my main is a Titan for the same reason I play a Paladin whenever I can - I will be the shield, I will be the wall. I will provide healing, revives, defense, buffs, and support. The enemies will break upon me as I take as much of their fire as I can stand - and then a little more. I will thin the herd of foes where possible, divert the attention of the heavy hitters so my allies can eliminate them, and run into the mouth of hell to bring back a downed teammate. I like being strong and able to dish out punishment - but I love being able to stand as an anchor point for my fellow Guardians. Thank you for your kind words, and I hope to see you out there on the frontlines. May the Light of the Traveler guide and protect you!
