Enter today’s 18.2.3 release, which contains several fixes and changes for the 12-player raid. Some of the mobs have seen their health nerfed, while the whole of the raid should run more smoothly from here on out.
The patch also made a few tweaks to the Summer Festival, stable-masters, and housing. It’s not going to make you want to throw a parade, but if any of these issues were stuck in your craw, now your craw is freed up for other activities.
