It's most likely because websites that tell you how to spec and everything don't say go mastery it says go haste, and there are few people now who play the way they want, in a way they enjoy (which imo makes them dps better because well they are enjoying it!) compared to people who google bis's, best spec stat reforges ect.
Overall from what I have seen and done personally mastery is a slight dps increase, especially on aoe, and especially with long execute phases.
