Doubles have all been turned into Quad.

BoS Recons have been turned into normal Hunting Rifles, the only special part about them is the scope which is now craftable.

All Survival Weapons have been turned into random rolled counterparts of their original guns. (As shown on the 1st picture - Even skins returned to them, literally making them identical to their crafted counterparts. The old event reward version of the Gutter is exempt from this, that was left untouched)  
\- This does not affect the OG roll-less versions of certain named guns. My Somerset Special and Daisycutter without rolls have stayed roll-less. (2nd and 3rd picture)

Fancy Revolver and Fancy Pump Action Shotgun gone, now just have a skin you can earn from Mutated Packs.

Invisible, NW Weapons, Paddles are safe, your old Rolled Blue Moon Weapons (Elder’s Mark, Kabloom, etc.) are also safe. Jet Pack Power Armor and Reverse Scout Armor is also untouched.

All named weapons now have unique effects but their stars are untouched.

I can check out some other stuff if necessary but pretty much unless specified all else is untouched, we’ve lost a few legacies but the damage isn’t as bad as people had thought.

PSA about Legacies for the people who haven’t yet had the time to check out the PTS.
