I always sort of assumed that our Guardian was wearing ceremonial garbs on account of the D2 banner having a bunch of Titans and a Hunter wearing the starting gear together and marking in what looks like a parade as well as the fact that the armor emphasizes the Class very greatly. D2 probably should have started with an in game cutscene with us marching in this celebration, or at least started the cinematic cutscene with Cayde looking down at the ceremony from the tower with emphasis on a specific guardian with their helmet on, implying that it was us. I still wonder why they had us start on our ship coming into the City and not have us start in the City streets, fighting the Cabal and protecting our people and slowly working our way up to the Tower. Personally, I think that would have been better, but that's just my opinion. What does a Kell know anyways?
