In this category enter : AA, Guardian's Ward Tactics (GW), Stagger, Sting, Retaliation, Whirling Retaliation (possibly Smashing Stab too, but I have not tested this)
The skills in this category are those that generate threat only through damage, with a linear relation between threat and damage. For AA and GW I also tried with a 2nd age belt that had a +3% PT bonus.
Results are here :
The "with +3%PT" line indicates expedcted values while wearing a 2dn age belt with said bonus.
As shown below however, It seems that such a bonus only gives about +1% PT. It seems to me that Perceived Threat is bugged. Either it does not have expected influence or has no effect at all, and the 1% difference we see is from the gained mastery (2nd age belt had some mounts/gems/runes while 3rd age had none), which then would influence generated threat more than by amplifiying damage, but also amplifying the multiplier coefficient.
