WTF Bungie. You have the DLC On Dick already and it will be pushed back from November do December? Why if it already exists in the game? lol lol lol

Clear is a strong word.

• Characters are better on Borderlands
• Classes are better on Borderlands 
• Weapons Proficiency are better on Borderlands.
• FPS gameplay is better on Borderlands
• Loot system is better on Borderlands
• Better story
• Better weapons

• Art Style is better on Borderlands 2

I can go on.

Of course some of it is unlocked. The glitch shows you everything already in the game and the stuff planned for expansion.

"requirements not yet met" = it's in the game right now
"expansion required" = DLC

Lore: Why we raid the Vault of Glass.

I decided to share it here because it's pretty awesome lore and deserves better than to be hidden. Having story unlocked through work is great and all but what I am sharing here is something your guardians would know prior to entering the vault. This is what should be handed to you as a brief before you'd set out from the tower.

Beneath Venus the Vex have constructed a massive structure that is acting as a meeting point of past, present and future. Their long-term goal is to basically unchain themselves from the constraints of a physical reality and turn themselves into a sort of epistomological computer virus in the very fabric of reality, incorporating the very IDEA of themselves into the fundamental laws of the universe. Because in this space, reality and time are starting to be altered, Oracles and Gorgons are basically quantum supercomputers that calculate reality and utilize a weaponized ontology to determine what is and is not real. This is why a Gorgon can look at you and kill you, because it simply unwrites you from existence. Oracles make changes and revisions to reality, and the Templar/Aetheon processes these calculations into existence.

The relic is the last, dying, desperate act of Kabr, a guardian who managed to send word that this was happening. He basically killed a Gorgon himself and hammered its corpse into a vessel for the Light, turning it into a shield that maintains a small space of stable reality around it. Throughout the raid, the Vex are constantly trying to separate you from it, throwing it into the past or future where it can't be used against them.

As for some stuff you should earn, here is a taster of info your raid could discover in-character while investigating the vault or getting exotic weapons.

All the guns and armor you find in the raid are the remnants of Kabr's failed raid and will give further info about their wielders and the events of the raid itself. In fact, some of the general exotics in the game once belonged to friends of Kabr too. The Super Good Advice machine gun is one such example but comes from the exotic bounties. This was crafted by a hunter named Pahanin who passed Kabr's warning about the Vault from Venus. After witnessing what happened to Kabr he became deathly afraid of being alone; he reckoned that he could only continue existing as long as someone was able to perceive him. So, to ensure that a mind could perceive him at all times he used an AI gun.
