It really can't be any truer spoken, how you said that those who don't main the Titan don't understand its underwhelming nature, save for the power granted through Sunbreaker. Many took the venture and saw for themselves, after it was announced that we would finally receive a more viable subclass. They scurried over to the Titan side in preparation and found just how much more difficult it was to stay on par with the remaining two class types. It's mostly the people who didn't, who complain for the purpose of a Sunbreaker diminishment. Because if they knew how intricate it was to do as well as they had, with Striker and Defender in year 1, they would realize how preposterous the proposition of a nerf actually sounds to veteran Titans.
