I hate to be complaining right now but I was looking through the new weapons and noticed 3 Vault classics weren't added into D2. The Pulse and Auto were really good, and with the same archetypes, they would perform much better in D2, especially with updated perks and a different sandbox. I never thought the Fusion was anything exceptional, but in D2, it would be so much better.
I don't see why these 3 were not brought back, a lot of people were looking forward to the auto at least, and now we don't get it. Why bother giving us most the weapons, but not all? You might as well have just given us Fatebringer
