I'm going to be honest, there isn't a single weapon that was sunset that can hang with any of the current drops in game. It's just another reason to complain over something that is meaningless.

That cost for the content that brought back Ghally also contains that activity that offers some of the most solid craftable weapons in the game like the BXR Pulse, Grenade Launcher, Shotty, etc. You are paying for a bunch of content not a single gun. I get not having your old guns is a bummer, but reacquiring most is not overly hard outside of Vex since it's a raid drop, but the changes to the raid rotator list makes it infinitely farmable the weeks that VoG is the weekly raid.
I mean, I am a very vocal person that I've hated some of the things they have done over the years, but if they just somehow gave everybody VoG weapons, there would be no reason to bring back the raid at all, plus the guns (outside of Vex) all have random rolls now instead of D1 where it was a static one.

about where/how to acquire anything specific I'm glad to try to help out with where to point ya.
