The quickest way to level up is to travel through the game's zones, completing all the quests you encounter along the way. Completing quests grants you Experience points, which will slowly fill in your experience bar with blue or purple. When the bar fills, you reach the next level. Alternatively, you could choose to run Dungeons or Battlegrounds, which are not covered in this beginner's guide.
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.
As it had been executed in Vanilla, Can Blizz launch the PvP rank system? As somebody who was wow classic gold around back then, and without needing to get overly hand-wringy, I feel that the position system itself supported some fairly unhealthy behaviors. That top rank took months of continuous grinding, and I mean constant, 10 to 12 hours each day, to the stage where people weren’t even functioning properly and everything out of that honor grind was excluded. There were things in WoW Classic that you had to forfeit your wellbeing and life outside of WoW Classic to obtain.
Additionally, Blizzard has said that there may be a couple of other factors determining who they allow in the WoW Classic beta sign up. For example, a player who has been subscribed to the game for a long time will likely have an advantage over a new subscriber. While the reasoning behind this may seem unfair, it is so that the team can get valuable feedback from longtime fans of the franchise.
