As someone who's leveled enough Alliance and Horde characters to fill multiple accounts, it remains to be seen whether replaying content I've seen many times before will keep my attention in the long term. But even the thought that it might suggests that for many people, this could represent a novel experience compared to the modern game, something at least worth a try.
Step-by-step class guides are on the way! The 1-12 Mulgore Guide is the first guide to get all the individual class steps. At the top of the guide, simply select which class you are playing and the page will dynamically update all the steps in the guide for that class (both text and images). The rest of the guides will be slowly updated overtime to include all the class steps, but you can see how it's going to work with the 1-12 Mulgore. I want to thank crazyK and his Placeholderguild for helping me out with the individual class content. They are allowing me to get the 1-60 Alliance guide done while also getting all the class steps done at the same time, so everything can be ready for Classic launch (hopefully).
So even though you can play a WoW Classic demo today, we’re not done quite yet. We have lots of capital city features to look at, such as banks and auction houses. We need to test our dungeons and raids to make sure the bosses’ abilities all still work correctly. We need to examine all of our PvP systems. But we’re committed to taking a close look at all of these and more as continue bring the classic game back to life.
