WoW: Classic is scheduled for August 27 (technically August 26 if you're in the Americas). The soonest that you can play it is starting in May, during Blizzard's scheduled stress tests. To opt-in you must have an active subscription on your Battle.net account. If you do, go to Account Management and select the Wow Classic beta. Keep in mind, there will be level caps during the test. The schedule is as follows:
This section gets a bit more in-depth as a Classic WoW Best Spec For Leveling Up Tier List, where certain classes can a have a really good spec for levelling while the other talent specs are more useful in PVP. Just below this, you can find links to our complete levelling guides for each class, where you can view to find all the information you will need to level up fast. This includes easy to gather weapons, locations you can farm mobs and a complete talent spec build we recommend while going from 1-60 in classic wow.
The Horde levels 50-60 guide has been rewritten and revamped. My 1-60 Horde leveling guide is now completely updated for the 1.12 Drums of War patch. As you can see it is about 15% larger than the 40-50 guide (single largest guide page yet). There is also a lot of route changes. I moved the entire Silithus section from level 55 to level 58, which allowed me to include a lot more quests for that zone. There is also a lot of other improvement to the route, including adding a lot more quests into the guide, mostly from Moonglade, Silithus and Eastern Plaguelands. This will make the final level 59 grind much shorter.
