Good god, just no. Thunderclap threat is not, and never has been, a split value. The threat each mob takes is individual. Think about this logically. TC has no innate static threat value. The threat it creates is determined ENTIRELY by the damage dealt. Please tell me how, if threat is based on damage dealt, the game takes the damage you did and then splits the threat created among the mobs for this one super special ability? The answer is that it doesn't. You do 'X' amount of damage to mobs 'A', 'B' and 'C'. 'X' is different for each mob, and thus the resulting threat, 'Y' is completely independent of any of the mobs. The reason why we don't spam it is because we can't. It has a CD. Spreading misinformation is bad.
