Apparently, there’s plenty of players eager to get started with Diablo 4 Season 1 despite what you have been reading since the patch dropped. As soon as the Season launched things ground to a crunch.
If you are trying to login to the servers then you will need to persevere. There are queues and there’s some real slowdown even if you do manage to get in. I have had the game completely locked up getting stuck on dungeon loading screens when undertaking the new questline.
There’s plenty of players who have got in but the experience is not great with stuttering happening all over the place. It’s a shame we are still at this stage whenever some new content drops for the game.
This will be temporary I am sure but you will have to stick with it. That journey to 100 is just going to take a little longer at this rate.
