The main thing stopping me from playing WotLK is the old subpar UI. If I could play WotLK with the Dragonflight UI, I’d be much more likely to play it. I don’t want to set up a whole bunch of addons to get access to basic features that should be in the game by default. I tried doing that in TBC, but the available addons for it made for an experience that was still significantly worse than the modern UI. Please bring classic WoW into the 20s. I’m not asking for gameplay changes, just changes to the way information is displayed.
What parts of the UI are you missing specifically?
