Just about everybody is preparing to see patch 4.0.6 on live realms tomorrow. The patch 4.0.6 patch notes have come a very long way from what they looked like when the patch first appeared on the PTR at the beginning of January. This is not a content patch, so it isn't heralding any new raids or instances, but the patch notes are quite long -- it's the first significant balancing pass since Cataclysm went live.
This patch contains numerous class balance changes, heroic dungeon balance changes, and endless bug fixes. If you want to be well-prepared for the patch and know exactly what's coming your way, check out the current patch notes just past the break below. Enjoy!
