It was sort of a smack in the face to go to old raids in World of Warcraft yesterday. Not in the slap-in-the-face disrespectful sense, but in the sense of just being extremely surprising. Every raid boss was suddenly sporting way too much health, and some more recent raids were suddenly impossible to beat at level 110 with decent gear. What the heck? Were we never meant to do Mists of Pandaria raids solo, even when they got patched to make it easier to solo some of them?
The answer is that it’s not you; it was an error. Due to the changes made to health calculation with the patch, raid bosses wound up with far more health than they were meant to have, and the team is looking into how to fix the issue, especially for raids in Mists of Pandaria and Warlords of Draenor. So you might have to wait a little longer for your transmog farming runs, but it’s a known issue that is getting addressed and fixed.
