In this form, there is much less wasted space and spells are no longer limited to three effects. But before we can load any database data, we need to transform the old data layout into the new one. This is not limited to spells, as almost every game system (including items, creatures, player characters, spawning, AI, and more) has had its database layout altered over the years.
Finally, a new stat I'm adding to this round-up: the number of moderator actions performed for the past 30 days! We performed ~6,000 actions 60 to 90 days ago, ~11,000 actions 30 to 60 days ago, and in the past 30 days we've performed a whopping ~19,000 actions. That's a lot of permabanned plebs, let me tell you. I assure you, the rumors of power-tripping mods hell-bent on getting our jollies from holding power over an internet forum is really, really true. Especially u/Undoer. But for real, y'all have unleashed the biggest zergling rush of posts and comments I've ever personally had to deal with, and we're a squad of about four Firebats in a bunker with one SCV doing our best to hold this ish down... wrong Blizzard game, but you get the point.
Blizzard has put out a ‘not a bug’ list that covers many commonly-reported features that seem strange to players, such as players and NPCs that are feared running faster, and quest objectives not being tracked on the map or minimap. Respawn rates for creatures is much slower than it is in Battle for Azeroth, and this is intentional – it reflects the respawn rate in the World of Warcraft version 1.12.
So we asked ourselves, would it still be possible to deliver an authentic classic experience if we took our modern code, with all its back-end improvements and changes, and used it to process the Patch 1.12 game data? While that might seem counterintuitive, this would inherently include classic systems like skill ranks, old quests and terrain, talents, and so on, while later features like Transmog and Achievements would effectively not exist because they were entirely absent from the data. After weeks of R&D, experimentation, and prototyping, we were confident we could deliver the classic WoW content and gameplay without sacrificing the literally millions of hours put in to back-end development over the past 13 years.
For another example of lighting, we looked at Elwynn Forest. We had a period in Warcraft’s history where we changed all the lighting equations and as a result, our environment artists had to take a pass over all of the zones to improve the lighting and take advantage of the new equations. To recreate the original experience, we had to rewind those changes. The first thing we did was restore the old lighting data. This brought us much closer to the original lighting—and with a few more changes to the distance formula, fog formulas, and some changes to shadows, we were able to bring things even closer to the original lighting.
