Possible 4.3 Threat Changes
Massive wall-of-text about changes to one of the most fundamental aspects of tanking - threat. Here's a brief statement from the post that summarizes the actual changes:
Here are the specific changes you’re likely to see:
Hotfix: The threat generated by classes in their tanking mode has been increased from three times damage done to five times damage done.
In an upcoming patch: Vengeance no longer ramps up slowly at the beginning of a fight. Instead, the first melee attack taken generates Vengeance equal to one third of the damage dealt by that attack. As Vengeance updates during the fight, it is always set to at least a third of the damage taken in the last two seconds. It still climbs from that point at the previous rate, still decays at the previous rate, and still cannot exceed the current maximum.
