At the time of writing, WoW Classic is currently on Period 5 of the PVE content program (see below) along with the Ahn'Qiraj raid was unlocked so, as soon as you reach max level, you will have access to a range of raids and World Bosses to tackle.
If you think you're ready to play World of Warcraft Classic, you'll want a subscription to achieve that. Unlike modern Warcraft that enables you to create as many characters as you enjoy and play with them up to level 20 without subscribing, if you're after the vanilla encounter, you'll need to put your money where your mouth is. The good news is that once dispersed, you will have access to both Classic and contemporary Warcraft.You can pay a month at a time or you opt to subscribe for longer which will operate out slightly cheaper.
