Keeping a massively multiplayer online game fresh and challenging for longtime players while simultaneously staying accessible and fun for lower-powered relative newcomers is always a challenge. In World of Warcraft, a hidden change to the way end-game enemies power up alongside players has unintentionally thrown that balance out of whack, and Blizzard is working on a fix.
Shortly after yesterday's release of Patch 7.2 for the long-running MMO, players quickly began noticing that high-end enemies were scaling up in power depending on the power of the gear the player characters were wearing. The specific power numbers involved seem to make it so that players could perversely make a fight easier by taking off their high-end gear and replacing it with slightly worse weapons and armor, reducing the enemy's health and power greatly in the process.
The change in how enemy scaling works took many players by surprise because it wasn't explicitly mentioned in the extensive patch notes Blizzard released yesterday. Furthermore, WoW assistant director Ion Hazzikostas spoke out specifically against this kind of gear-based enemy scaling in a Twitch interview last year.
