[Update #2]: Diablo 2 Resurrected's Patch 2.4 is adding ranked Ladders and buffing a bunch of niche builds.
[Update]: It took quite a while, but things appear to be rather stable now.
Unlike Warcraft 3: Reforged which has fundamental issues holding it back, Diablo 2 Resurrected is a remarkably faithful remaster of the original game. It looks better, it plays better, it sounds better, and most importantly of all, comes with some handy quality-of-life features like the ability to play with a controller.
Yet despite all of that I've not been able to truly enjoy Diablo 2 Resurrected for over a month now. During the first few weeks the game was plagued with numerous server issues that only seemed to get worse with each passing day. Blizzard took a while to react to these problems, but they did eventually fix them and I was able to play for a little while without any trouble... and then the queues happened.
At pretty much any point in the day Diablo 2 Resurrected now has lengthy queues to simply log into the game, with many of them taking well over 30 minutes to fully resolve. My record is waiting an hour in the queue, finally logging into my Assassin, only for the game to disconnect me and send me right back to the queue again! And judging by some of the reports online, I appear to be among the luckier ones in that regard.
I'd love to tell you this story has a happy ending, but Blizzard is yet to respond to these issues, though they are undoubtedly working on fixing things. Still, if you're even considering buying Diablo 2 Resurrected in its current state, I would highly advise to wait until everything is sorted out as otherwise you'll just end up like me - frustrated.
Once things improve I'll make sure to let you know, but for the time being all we can really do is sit, wait and mourn the loss of the once great "Blizzard polish" that they rightfully prided themselves with.
