Shouldn't Expose Weakness and the Assassin mastery have their trees switched with each other?
Assassin is pretty ferocious and offensive but it's in the Cunning tree Expose weakness is a good Support mastery but it's in the Ferocity tree

I believe it is more to make the trees more open to several classes.
Some might want want Thunderlords over anything in ferocity and if you are playing an assassin the middle tree is actually a really good option.
