Stumbled across this thread on Reddit and found it pretty interesting. I haven't played FO76 yet but from the looks of things Bethesda is trying to throw in changes that look to be intended to make gameplay slower and/or make it more difficult to get things done quickly:
Workshops that produce fusion cores have had their rates reduced to one core per hour from 10 cores per hour.
Workshops that produce ammo have had their production cap reduced from 400 to 200.
Extractors now produce ore instead of scrap (it takes multiple ore to equal one scrap, so this is a big one), with the exception of lead.
Fusion cores drain quicker, though the actual percentage difference is not determined yet since it's not on the patch notes.
Enemy spawns have been altered, drastically. They used to spawn when anybody entered the area, even if other players were already there. It appears that enemies now spawn if and only if no other player is immediately near their spawn point. For me, this is good for some circumstances, but very problematic for farming high-level areas for XP. This has significantly reduced the effectiveness of nuke zones as a means of level-up.
Again, I haven't played the game so I can't speak to the impact of all of these, but more generally it's interesting that Bethesda would be nerfing stuff without thoroughly documenting what they're doing in patch notes. Obviously there's a conspiracy theory (they're stealth nerfing to avoid community blowback when patch notes are released), but it seems more likely that they're just scrambling to fix as much stuff as possible and aren't quite as used to documenting patch notes for an online game as they are for their offline titles (I think ESO is made by another company?).
People who play stuff online have come to expect that each change in a game is detailed in patch notes and get REAL MAD when they aren't. Patch notes for some games can get ridiculously long but from a community perspective it's better to be thorough than to be disorganized like this. It's also just weird that Bethesda would be trying to nerf gameplay in the wake of a launch that could fairly be described as disastrous for them. Obviously what's good for gameplay is good regardless of timing but it's just weird timing all around.
