Here I have two cases. The only difference is %AD. So empirical AD efftctiveness (107 vs 15) is 25/13 ~=1.9 which is pretty close to theoretical estimate (1+5*0.2*1.07)/(1+5*0.2*0.15) = 1.8 You can simply calculate your AD buff coefficient of an AOE skill as 1+(n-1)*0.2*AD where n is the number of mobs within the 10 yard radius. As you can see, this affix is pretty useful if you are running with pulling skills like cyclone strike, black hole etc.
