The addiction to loot is starting to wane for me. They really need to beef up their goddamn lore. When a stupid Penny-Arcade comic has more thought provocation than their whole game does - something is wrong.
I can only kill things for so long without being given a bit of the elusive story carrot.

There is some very cool stuff in the grimoire cards but they need to put that in game. Maybe allow you to look at the speaker's library and it can show your grimoire cards.
For example.
The lore behind Eris' lost fire team, gathered from item descriptions and grimoire cards.
She had a fireteam of five.
The Titan, Vell Tarlowe.
The Hunter, Sai Mota
The Warlock, Eriana-3
The Hunter, Omar Agah
Eris Morn, unknown class(Warlock?)
These five were members of a secret organization known as "The Hidden", pioneered by Ikora Rey. They were an elite team of Guardians who's mission was to infiltrate the darkness and provide intel from the lost colonies They were sent into dangerous situations with little to no support. Their last mission was to dive deep into the Hellmouth and eliminate Crota while he still slept.
To get into the Hellmouth, they needed the help of the exiled Warlock, Toland the Shattered. His research had deciphered the Hive runes and know how to open the gate, so they sought his council. Toland described the Hive to the Hidden, explaining their connection to Crota and how each of them contained a piece of Crota's soul. The team would need to kill all of them. The Fist, the Heart, the Hand, the Might, and the Will.
So they set off to defeat them all and exterminate Crota once and for all. But the Hive would be too much for them, and only Eris would return alive.
- Vell Tarlowe was overwelmed by the Hive Wizard, Verok, and her army of Thralls. Its possible that the fallen Titan we see on the Moon outside the Temple of Crota is Vell, and the Ghost inside is his.
- Sai Mota the Hunter died fighting Omnigul herself. She killed him, mocking his allies as she did.
- After these two fell, Eriana-3 vowed revenge. She would become cruel and merciless, capturing a Hive Wizard and torturing her in an attempt to discover the secret to killing Crota. Eventually she lost herself to the darkness and became a Hive Wizard herself; Ir Yut, the Deathsin.
- Omar Agah's fate is unknown. Presumably he died, but how it happened is uncertain.
This left Eris Morn alone. Amidst the chaos, her ghost had fled. We actually received a grimoire card detailing him earlier, with "Ghost Fragment: Hive".
Eris hid in the Hellmouth for years, learning to use the shadows as the Hive had. It corrupted her and drained her of light, but she persevered until the moon's defense grid reactivated, and Rasputin took control.
You are the reason she survived and made it back to the tower. Had you not activated the array on Earth, she would have been trapped forever.
Toland is still alive, and Ikora is looking for him. Presumably because of his involvement with The Hidden.
