Another hurdle we had to overcome was how to store and merge our data. World of Warcraft has multiple updates or patches in development at any one time, each in a different stage of development. If an art asset or terrain file is added to one patch, the system is designed so that it also automatically shows up in later patches. This meant that If we had simply inserted a new patch for WoW Classic into the current development environment, we would have overwritten things like the current broken dam in Loch Modan with the previous intact version—and as you can imagine, this would have caused issues for Battle for Azeroth.

Players will start from level 1 and will progress through level 60 with real, Blizzlike x1 rates. Old PvP battlegrounds are: Warsong Gulch, Arathi Basin and the famous 40vs40 players Alterac Valley where battles were known to last more than 24 hours. 20 and 40 man raids will be available for Molten Core, Zul Gurub, Blackwing Lair, Ahn'Qiraj 20 & 40 and the original Naxxramas raid in the Eastern Plaguelands.
Nov 15 The most hardcore thing you can do. In vanilla? I have a few things that could be it. Playing on a perma death PvP server and kill kel'thuzad. Without dying even once. Being able to kill a mage/rogue/warlock/pally in all BiS gear Soloing a high end dungeon boss like rivendare or dark master gandling. Leveling to 60 with no gear or weapons or pet of any kind. That is by far the most hardcore, life threatening thing you can do in vanilla wowHavell7 Nov 15
