So now with Crow being the new hunter vanguard things are no longer balanced like they were before. Think about it, before Cayde's death we had 3 vanguard 1 of each character type & each character race. But now with Crow being the new hunter vanguard we have 2 awoken & 1 human vanguard and no exo vanguard. Also during the final shape Zavala's ghost died and Zavala lost his connection to the light and is no longer immortal like the rest of us. Because of this I think Zavala is either going to be killed or is going to retire as the Titan vanguard and is then going to be replaced by Saint-14. Saint is both a Titan and an Exo so he would be the perfect candidate to become the next Titan vanguard. Also they could then make Osiris be the Trials Of Osiris guy (which would actually make sense since trials is literally named after him XD). So yeah in my opinion this is what I think is going to end up happening in the story over time as right now things are no longer balanced with Crow being the hunter vanguard as he's also awoken like Zavala and isn't an exo like Cayde was. I also personally think that Saint would be a better option for the titan vanguard than Zavala (but I'm also slightly biased since my favorite race is the exo's and my favorite character is Titan XD). Please feel free to leave your thoughts and opinions down below and share any theories you might have on what you think will happen next in the story.
