Like, I get not following along with Blizz on social media, but I’m still shocked by the sheer number of people who don’t even check out wowhead.
The pre-patch overview has been up on WoWhead Wotlk for MONTHS now:
Along with all the relevant dates for when the Zombie Plague starts and ends, as well as when the Scourge Invasion starts and ends.
And sure, the Scourge Invasions started 3 days early, but Blizzard has admitted that was a mistake. All other dates are still accurate.
