The Enigma Order

It seems that the latest build brought an interesting change to TBC instances : all monsters in TBC raid instances had their health points reduced by 30%, bosses included. We don't know yet if this change is final, but below are a few exemples of changes for some of these instances, more values will be added as we go through the instances. Feel free to contribute with your own lists in comments.

Note : The change isn't confirmed by Blizzard yet. We don't know if this change will be pushed live, and we don't know when it will happen but we might see this change shipped with Patch 3.0 before the release of the expansion
