Can someone fill me in on what happened to this games positive reception?

The title might seem rhetorical, however I really am asking as I have been very out of the loop on this game for a while. I have very severe ADHD, and go through different phases of games that I play very often.

A few months back, I was very into ARPGs, playing stuff such as Grim Dawn, Diablo 3 and Torchlight 1 and 2. As I was playing those games, I was also on the lookout for others, and this game kept getting mentioned in every single thread a saw regarding the genre. Pretty much all I heard were very positive things, and it got me excited about the game, and I had planned to pick it up shortly after it's launch. I do vaguely remember that when it launched, it had alot of server issues or something and received alot of mixed reviews due to that, however I fully expected that to shift back to postive once those issues had been sorted.

Well, I never picked it up back then as I kind of drifted off into playing other games (mainly roguelites, and multi-player games like rocket league) and I have recently been getting the itch to play a new ARPG, but I have been hesitant to pick this game up as I see it is still a very mixed reception game it seems.

Basically title, I just wanted to know why this game went from all the positive praise, to all the negative (really reminds me of The Division 2 if anybody has played that around launch, you would know the same thing happened to that game as well where it had nothing but positive support then turned to a cesspool of negativity)

All replies are appreciated in advance. Thanks!
