He has some of the best dialogue in destiny two aside Cayde-6 dialogue, he is not as funny but he has a sense of fun to him for example hiding things from Zavala like gambit.
It would be nice to see a small storyline where’s Zavala finds out about Gambit and he is totally against it at first, but when he finds out how beneficial it could be to the guardians, Zavala and Shaxx except The Difter fully onto the Tower....... but even as he becomes one of the Towers Factions, he still has small quest behind the Zavalas back that allows guardians to acquire illegal and powerful gear.

Theres lore attached to the Gambit weapons indicating the Drifter set everything up to prepare guardians for a much bigger threat.
