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.
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.
