heh...they can double it, triple it..or even quadraple it...main thing is..whether the legend is gonna roll good..
no worries....it'll just make the variance of RMAH value longer, for the piece of legend can start from 1.25 to 250.00...

bad stat roll = 1.25
superb stat roll = 250 (or if higher than 250, then it will be in gold)

Values are on stats..not on item

p/s: "Double the legend drop rate"..not a specific legend...it is any legend, those in inferno 1.05, any lvl 58 above legend.. still a long list also... no complain though..still enjoy whenever sees a brown/green drop , beat those yellow/blue better than nothing

peace y'all...
