It's almost like they want the damage checks in fights to be done by *gasp* the damage dealers!

War DPS was too high compared to the other tanks, they have now been brought in line, it's as simple as that. They cant just keep buffing the lower tanks to meet the top tank as well, since that results in the gap between tanks and real DPS being too small. On top of that, as an actual tank and not a roidhead DPSDPSDPSDPSDPSDPSDPSDPS warrior, you guys got a MASSIVE buff.

Remember, at the end of the day, you are still a tank, not a DPS. Stop pretending to be something you clearly are not meant to be. It's outright toxic for the raid scene.
