This change actually has been out for a while, I've been on the layout for the past year or so. It's just recently they forced the existing user base onto it where before it was in opt-in, once you get used to the layout it's actually quite a bit better in my opinion it goes with the mobile flow a lot better, it's just getting used to it for the first week or so sucks. It's all so much better than their original redesign which had all of your servers on the bottom with your DM and you had to swipe back and forth between the servers to try to find it which was absolutely atrocious
