Because she exposes how poorly the rest of the story and characters are written. I think her character is awesome. I think the way she was developed over time, and has remained as consistent as seems possible in Destiny, is awesome. So I believe she is the shining example of why pretty much ALL of the other characters, well, suck. Ok, maybe Devrim and Drifter are good as well. But the rest? The Vanguard "leadership" is way too passive. The side characters that we are supposed to care about are far too concerned with personal drama to be useful. Bungie... Ana is a terrible character. She has never had an interesting or compelling story. Let it go. It isn't going to happen. Her sister is where you need to put the focus. Saint and Osiris's relationship is not compelling. Not because they are in a relationship. But rather because THEY NEVER DO ANYTHING TOGETHER. Two of the most experienced and powerful allies that pretty much never do anything of note as a TEAM. You know, that whole Fireteam thing you abandoned after Cayde. The whole Fireteam thing that bonded groups of characters, that basically made up some of the best motivations in the story. Cayde, Zavala and Ikora. Used to be a team, now either dead or, might as well be dead. Eris's Team. A central point and cautionary tail for how to face the mortality of being "immortal", Saladin's Iron Lords. An epic story, which see's us join him in the end and earn respect, while respecting the mistakes of the past. And ultimately the Alliance. Our uniting with our allies. OUR overall fireteam. House of Light, Caital, even the Awoken to some extent. THAT is the story you need to keep telling. You introduce new characters on Neomuna. They essentially conceded control of their defensive operations to outsiders, with Osiris being an -blam!- the whole time. Make one of them completely out of place in terms of tone and presentation, make the other so minor in terms of our interactions that their, um, "arc" has a "well that just happened" vibe for everyone including their partner. Huh? But Caital? She understands what is at stake. She knows our enemies. She has sacrificed and taken SPECIFIC actions to aide us. She is a leader. She respects our power and OUR contribution. Like actually acknowledges it. All the while, everyone else acts as if it's just another day in the tower. C'mon man. Stop telling us who we should care about and why. More developing of characters that WE care about because of what they do. EDIT: I wrote this before doing the next to last mission where Caitl fights with your guardian. Now I think she is even cooler. That was bad -blam!-.
