Don't just lump everyone together as an unthinking herd. The changes are pretty extreme and was was lost is pretty substantial. It's a different game now, going in a different direction, and that direction is definitely flipping off a good chunk of players. The old game had a ton of problems and needed large and small fixes in a really big way. I could make a huge list of needed changes that wouldn't forsake what I enjoy in the game. i could also make a short list of trivial fixes that would address a lot of the big problems this was for. None of those are what happened, though, because the developers want a different direction entirely, and that direction is quite explicitly "less thinking and fewer options for players" and "less effort for developers". On top of that, the game is now even more of a broken mess, the changed story sections are super dull, and most of the supposedly good stuff in the update is several to many months out still. The game has been dumbed down. The developers are lazy, and doing poor work.
It's really not a "change is bad" situation when a company deliberately tries to take out big aspects of a game that players enjoy, especially when they do a horrible job of it. It's like if someone took Fox's mom out for a makeover, and she came back older, fatter, and with her mouth sewn shut.
