Did the math on threat. 30% for def stance. Add 15% for 3 points into anticipation. .7*.85=.595 1-.595=.405% so 140.5% Now for +2% threat. .7*.85*.98=.5831 1-.5831=.4169 so 141.69%. Difference of adding +2% threat was 141.69-140.5=1.19 or if you like 1.19% for easy comparisons.
BTW i think they round off too. So def stance and 3/3 anticipations would be 141% and with +2% threat it would be 142%. Hmm doesn't 2% threat really look like crap now since it's only really a 1% increase assuming the rounding. Best case 1.19% increase. Worse case 1.00% increase. +2% threat is not looking so good to me. No wonder i prefer 15 agility.
God hope this math is right or i'm wasting my time. Fairly sure it is. But /shrug
