why oh why are the wrestling skills of the Diva's so bad these days?

as 80% of the diva's today can't even wrestle, as now a days they are más beauty puppets then wrestlers.
like that Eva Marie for example, why is she in wwe when she not even can Wrestle?
don't get me wrong all the women in wwe are great in what they do, but wrestlers they aren't really
I liked the Diva's más in the era from Trish Stratus, Jazz, Victoria, Lita, Mikie James, chyna, etc... those where women who really could wrestle
